HABITAT: deep slow marshy-bank river through residential area. OBSERVER: Frederick W. Schueler, Aleta Karstad Schueler, Orion Clark, Emily Upham-Mills, A.Bouchilloux, Phil Scott. 2009/182/d-, visit () (event). natural history, wade, dipnet. WAYPT/Y 007, Tay Macroinvertebrate & water chemistry survey. River at one-lane private bridge with iron railings. Force 3 breeze rippling the water. Appears quite deep, about 30 metres wide. Bed of the main channel is sand & gravel On the west bank near the bridge, the house has a mowed lawn, to within a few metres of the water edge, where the shore becomes steep and is tall grass, bushes and Vitis riparia (Frost Grape) vines. They have a deck built out on pilings - different levels with railings. The rest of the shore is natural along both banks. Looking south. Fred and Philip start by checking the southeast bank, where the shore is reedy emergents and a few isolated patches of Pickerelweed with spikes of purple bloom, Lythrum salicaria (Purple Loosestrife) behind, among grasses.

Narrow margins of Nymphaea odorata (Fragrant White Water-lily), with some white flowers among the pads further down on the west shore. Trees along shore look to be Acer (Maple), Fraxinus (Ash), Salix (Willow). Fred and Philip found lots of juvenile Rana (True Frog) in the marshy edges. At least one was a Leopard Frog, the rest were Green Frogs. A lot of bark fragments through the muck. The Purple Loosestrife is moderately chewed up by Galerucella, but is blooming well due to the wetness of the season.

Looking north, downstream, the shore is natural and marshy, one big bank of Pickeralweed and grasses with yellow heads glowing in a halo above the leaves, magenta flames of Lythrum salicaria (Purple Loosestrife) picked out by the sun - treed with Maples, the shoreline posted regularly along with old rotted stumps and roots just at the water edge. The west side has houses and lawns, the first few leaving a riparian strip of several metres, and the next few, out of sight, having lawns mowed to the edge. Fred and Philip have found a thin Unionid shell fragment, a golf ball, a beer bottle, and a 40 cm Watersnake seen by Philip.

10:05, Emily and Astrid arrive

10:15 PHOTO Fred, Philip, Orion at north east shore, with dip nets, Fred found one baby Elliptio complanata (Eastern Elliptio), and a lot of Campeloma decisum (Brown Mystery Snail) about a dozen collected, buried in fine sand below and east of the bridge, in the shade of a big Silver Maple.
A pair of Bombycilla cedrorum (Cedar Waxwing) are insect catching from a tree by the bridge.

10:25 Philip scares an 80 cm Nerodia sipedon from the rocks in the bridge abutment into the water upstream of the bridge.

10:35 Emily and Astrid, hunting below the deck on pilings, saw three Damselflies, one blue with a green tail, and another colour, blue-grey all over flying around each other, may have been sex difference. Cardeulis tristis flying, 2 large 15 cm Bull Frogs, one 4 cm Green Frog, and a handfull of dead Campeloma shells.

FWS & Philip went upstream along the S shore about 100 m, blindly groping in muck and finding no shells. there's bark and woodchips in the muck here, but no Campeloma.

HABITAT: slightly green-turbid river with coarse sand bed with angular broken rock, through forest. 2009/182/e-, visit () (event). natural history, dipnetted, wade. WAYPT/Y 008, Tay Macroinvertebrate & water chemistry survey. We walked about 150 metres down a slightly sloping trail from the house through a Maple forest of all ages of trees from 50 cm dbh trees to saplings: Coral Fungi in clumps, and especially single 'fingers' densely all along the track and through the woods. Scattering of other mushrooms, including an Amanita right at the site. The soil was hard packed with some tough moss on it - looked rather clayey, dry surface surprising in this wet summer. Reaching the sunlight of the river edge, passed a path to the shore where Fred was dipping with his net, and went downstream a little along the trail, to a screened gazebo standing in the forest, then took a little path to the dock. PHOTO at the dock

Green Frogs scattered along the shore, none calling yet. Gyrinidae swimming in a cluster near shore. Bullfrog 8 cm in water's edge (Emily). Fred says clear visibility is about to one metre, but the water is too cloudy to see the bottom deeper than that. Coarse sand bottom with angular broken rock, very little organic sediment. The far shore looks as if it is being grazed above a metre from the water. Parus atricapillus (Blackcap Chickadee) singing. The forest is mixed right along the shore, with some Cedar and Spruce as well as the Basswood and Poplar.

11:15 Emily sees a live Lampsilis (Lamp-Mussel), displaying its orange fringed mantle, opening and closing rhythmically, 85 mm x 54 mm. She also picked up a crayfish claw.

11:15 Fred reports a couple of plants of Wild Rice, caught one Orconectes cf obscurus upstream about 50 metres from the dock.

11:16 Astrid comes to the dock with live clams to measure.

Fred says we have been finding some great big stonefly larvae. Most of the aquatic vegetation is Vallisneria, scattered out there, and swathed in adherent algae.

A group of teenagers swimming in the deep fast water between the dam and the bridge. One of them comes to join us, using one of the glass bottomed buckets.

On the east side of the bridge the mud is churned by Cattle tracks, where they evidently come to drink, though none are present now.

An island 150 m downstream has a clump of Acer saccharinum (Silver Maple) on its upstream side, and is otherwise all Grass and Lythrum salicaria (Purple Loosestrife). the river here has a broken limestone bottom. Emily saw a Crayfish with the viewing box, but couldn't catch it - then she an Astrid both used viewing boxes and didn't see any more Crayfish.

A beautiful old stone house with a rust-brown door and a green roof, and Hydrangeas by the front steps, beyond an arched wooden bridge with massive rusty steel rails. PHOTO

Fred has gone downstream and is poking under stones along the shore. Sparganium (Bur-reed) growing along the shore, only one flowering spike of Purple Loosestrife, near the bridge. Mixture of Raspberry, Grape, and Jewelweed clambering over the loose rocks at the bridge abutment.

This is the most idyllic spot yet. There is a house on the northeast side, that I can't see much of except the roof and an internet tower. They have left a riparian strip of a few metres along the river, thick with bushes and trees - Silver Maple it looks like, mostly. A wider strip is left by the Wildgoose household, except for a canoe-launching access of trampled Iris (Iris) leaves, it is 10-20 metres of wildness between the lawn and the river edge. Tall deciduous forest borders the river looking downstream to its northward curve, and a beautiful Silver Maple leans out, shading nearly half the water's flow. The water is very clear, and pale yellow in colour, and moving swiftly, about 80 cm per second. The bottom is a jumble of every size and colour of rock and gravel

05:01:27 PM: Philip brought two live clams and measured them with Orion's plastic calipers.

After working upstream of the bridge a bit, Philip has waded down to meet Fred, with a viewing box. They are about 150 metres downstream, nearly where the river begins a gentle turn.

Tay Macroinvertebrate & water chemistry survey. This weeklong survey went pretty well though it was tiring because it was so hot and humid. We had the best kind of places to work, though. . . with our feet in running water - 27 different spots on the Tay River! Aleta only got one painting done though, because she was doing the computer input for the observations of the volunteers, and had to keep them supplied with bags, do all the photography, and answer many of the questions, while Fred was out searching for the piles of shells left at the Muskrat feeding spots, and turning rocks for Crayfish. At many sites Fred filled out a datasheet independently of the datasheet-like account Aleta and the volunteers composed, and these are merged in the datasheet records.

Orion took water chemistry with a Hydrolab Surveyor Model 4. . .

The computer we bought for this trip is an Acer aspiron 1 that cost about $250, very small, light, and capable. Battery life only about 3 hours, so we'll order an extra to keep on hand. It can be awkward to have to run the vehicle, parked, for the computer to recharge - it's not always a good time to take a break, especially when there's not much driving between sampling stations.

We had about eight volunteers, some days more than others - this also proved handy for us as the Subaru stationwagon had to have repairs at a local garage on two separate days - once when the electrical ground failed and it wouldn't start, and next when the rear brakelines failed and had to be replaced. Otherwise, it's a great field vehicle, holds a lot of gear, and very stable on its four wheel drive. We spent most of the nights at

"Damiano, " founded by Mike Nickerson is now jointly owned by eight people. Only one of the owners lives here - Antony Powell, who sleeps in a trailer and has his studio in an old schoolbus, is a sculptor and master gilder. We enjoyed visiting with him. We slept in "the house" which is on solar electricity and is really lovely inside (designed and built by Mike Nickerson, who made my Biodiversity tables) and cooked and ate in a huge open-air kitchen (not even any screening) with a large chimney that operates as a stove (a big steel grill and grate about waist-high). This open air kitchen is all equipped, with a dark pantry on cool granite rock, and shelves with dishes, knives, cutlery, cutting boards, draining racks, a sink that drains underground toward the garden, etc. What a delightful place to prepare meals!

The main floor of "the house" is an open-concept kitchen and livingroom, and both floors have a wall of windows facing the pond. We slept our top bunk downstairs in the sleeping quarters of the house. All the woodwork is natural, all corners rounded and smooth with a glossy finish.

The toilet in the house and the outhouse as well, have buckets managed with layers of fine sawdust, that you take out every few days to the compost pile past the garden, and layer with straw. No smell at all, in the outhouses or the compost pile. The pile produces quite a bit of heat, and makes soil quickly, though the nutrient status of the grounds is low, suggesting that the site isn't used very much. They alternate two piles, and call the resulting soil "humanure". They certainly don't have to worry about contamination of the well, which is about 200 metres away, on the other side of the kitchen.

DATASHEET SUMMARY: Land ownership is municipal picnic area with private land all around. The locality is based on global positioning. The diel period was midday. The sky was lightly overcast. Sun hazy cloud cover 90%. There was no precipitation. The wind was breeze Beaufort 2 Force. Weather for the past 48 hr was seasonally normal temperatures unseasonably wet.

Air temperature 25 C 10h30 on tree trunk in shade.

The site was in a shallow valley. Bedrock was metamporphic gneiss. Upland substrate was not closely observed but seemed sandy. Soil moisture was assumed to be at field capacity. The terrestrial vegetation was successional parkland (70% wooded). DOMINANT SPECIES: Acer rubrum (Red Maple) / Acer saccharinum (Silver Maple). Human impact on the site included recreational picnic area and old logging waste in bed of stream.

Wetlands were fringing marshy areas. Dominant wetland plants were: Pontederia, and Sagittaria (Arrowhead) in bloom. Development stage of Typha (Cattail) was mature seedheads.

Water at the site was permanent natural pool & riffle river. Water level was high. The bottom was bedrock boulders cobbles gravel sand mud bark chunks; about 20% actual bedrock, 20% sand and chunky sawmill waste & cobbles.

Water quality was clear. Spaces under rocks were exceptionally clear of sediment. Water movement was medium fast. Dominant aquatic plants were submerged Potamogeton (Pondweed) blooming, some Vallisneria americana (Water-celery), and other liner-leaved species patchily in sandy substrates, with scattered Hydrocharis morsus-ranae (European Frogbit) along the shore.

Capture was by hand & dipnet. Cover checked included flat rocks round rocks - all underwater the shores are submerged.

09:41:54 AM: Nicodemus Mulder sees several 15 cm "Perch, " plus a "whole bunch of probably Perch fingerlings 6 or 7 mm, and in the reeds, a school of even smaller fish, about 3 cm - about 20 of them. No one else sees any Perch, and Nick is unable to give field marks for this identification. Chris sees a "foot-long Small-mouth Bass"

09:56:41 AM: Lucy Welch came up with a large shell of Lasmigona costata (Fluted Shell). Alain Gauthier found two water penny, 5 and 6 mm, and a Sialid (Fish Fly) larva, Caddis Fly larvae with stick cases.

Frogbit was found about 15 metres upstream along the east bank.

Sphaeriid pair of empty shells 14 mm long, containing a smaller sphaerid of 5 mm long, different species.

The lady of the house says the turtles come up in the morning from the river to the house, to lay in the field and near the house, digging holes, oblivious to observers and even mowing. Observed Painted and Snappers, but has not identified a Blandings Turtle yet.

She is asking Fred why the mature Ulmus (Elm) americana at the waters edge is dying, he says Dutch Elm Disease. She has had Butternuts dying of canker as well.

DATASHEET SUMMARY: Tay Macroinvertebrate & water chemistry survey, on private land. The locality is based on global positioning. The diel period was morning. The sky was clear with bright sun cloud cover 5%. There was no precipitation. The wind was Force 3 breeze.

HABITAT: rushing river running from village & fields into Typha marsh. 2009/195/-, datasheet (datasheet) (event). nat.hist., wade, dipnetted. WAYPT/Y 043, Tay Macroinvertebrate & water chemistry survey. DATASHEET SUMMARY: Richie Farm, close to the Bolingbroke Bridge, a traditional right-of-way, down a grassy lane, just NE of the corner where the old school/church historical building is, through private land. The locality is based on global positioning. The diel period was midday. The sky was clear with bright sun. The wind was breeze Beaufort 2 Force. Weather for the past 48 hr was seasonally normal temperatures unseasonably wet.

The site was in a shallow valley. The terrestrial vegetation was coniferous deciduous parkland (30% wooded). Human impact on the site was minimal; it's a traditional canoe launch site. Site wetlands were fringing riverine marsh. Dominant wetland plants were: Typha (Cattail), coming up from 70 cm depth - not sure if this is flooding or not. Development stage of Typha (Cattail) was mature seedheads.

Water at the site was permanent natural river. Water level was very high. The bottom was boulders & cobbles. Water quality was clear. Spaces under rocks were clear of sediment. Water movement was fast. WIDTH: 20 m LENGTH SAMPLED: 150 m MAX. DEPTH: 1.5 m DEPTHS SAMPLED: 0-1 m. Dominant aquatic plants were submerged brush-leaved Potamogeton (Pondweed). Capture was by hand & dipnet.

High water rapid clear stoney river through marsh & forest. Orion: "The highest saturation of oxygen of any place we've done so far - the first one that's over 80%"

Lucy found Elliptio shells, that look like Strophitis, and then two live ones.

FWS waded some distance downstream, but didn't see & couldn't do, anyhthing in the rushing metre-deep water.

340) T 08, Tay R at Bolger's farm (2 nd Conc. Bathurst). (200m alg river), 31C/16, 44.82644N 76.35945W TIME: 1502-1604. AIR TEMP: 28.5, sunny, breezy. HABITAT: rocky Beaver-influenced clearwater river in Thuja/mixed woods. 2009/196/-, datasheet (datasheet) (event). nat.hist., . WAYPT/Y 030, Tay Macroinvertebrate & water chemistry survey. This is the place with the long forested lane that we tried yesterday but it threatened thunderstorm. We parked about 100 m from the river, and walked into a field access, taking the mowed hayfield down to the river. Beat a path through the rank vegetation along the shore to access the river where there are a few emergent granite boulders, but AKS went upstream a little to the shade of Birch and the Cedar that overhangs the river, to find an office for the notebook computer.

DATASHEET SUMMARY: Land ownership is private. The locality is based on global positioning. The diel period was midafternoon. The sky was clear with bright sun cloud cover 30%. There was no precipitation. Air 28.5 C in shade of lane, where we parked. The site was in/on shallow valley. Bedrock was granite. Upland substrate was not assessed. The terrestrial vegetation was Thuja -lined woods along river; hayfields inland. Human impact on the site included current haying streamside-chair recreation.

Wetland plants were Ponterderia in muck downstream. Water at the site was permanent natural Beaver influenced river. Water level was high. The bottom was bedrock, boulders, cobbles, gravel, sand, loose detritus/peat/muck. Water quality was clear. Spaces under rocks were clear of sediment. Water movement was fast. WIDTH: 15-30 m LENGTH SAMPLED: 200 m MAX. DEPTH: 70 cm DEPTHS SAMPLED: 0-70 cm. Dominant aquatic plants were submerged filiamentous algae. Capture was by hand & dipnet. Cover checked included flat & round rocks.

03:23:07 PM: Lucy and Drew came to sit on the rocks by the shore, where my office is in the shade, and spread out their clams on the flat granite rocks. The only clam found alive is a Lasmigona costata (Fluted Shell) of 100 mm, which Drew found in the muck near where they entered the river, downstream several metres from my Cedar forest office. He said that it was deeply buried, and hard to extract. PHOTO. I also took a PHOTO of a shell of one bearing a thin, minutely spongy encrustation of something orange, in overlapping colonies of about 6 or 7 mm in diameter. It was near the margin of the shell. Collected into a ziplock with some water. The pile they brought back contains several Elliptio and parts of at least four other Lasmigona costata. The only crayfish they found were part of a shed skin and a single large claw.

Just where I am, the river narrows in a riffle, and then where Orion took his water chemistry, it widens out on both banks into little marshy backwater bays.

03:35:13 PM: Fred just brought back a sample from a shell pile just across the river in a backwater behind a ledge, that was a whole lot of beaver-modified sticks and cut green branches. A lot of the shells were in shallow water, so probably a Beaver pile. Includes Stophitus and Ligumia recta (Black Sand-Shell). He'd gone downstream to the ledge below this current riffle without seeing anything but Elliptio. There's a bed down there, on this side, that's very soft organic muck. It might have Pyganodon/Utterbachia, semi-floating unionids, and he would have made a mess of that if he'd had the wire net - very low density muck.

03:40:28 PM Fred was going out towards the riffle to turn some stones for crayfish, and said "Aha!" Reached into the water and came up with a shell of Lampsilis radiata silliquoidea.

NO:Dreissena seen here. Fred caught one Orconectes (Orconectes) - and then a few more, in a shallow flat area with moderate current, and algae streaming off the rocks.

Then we walked out of the ideal office area barricaded with Xanthoxylum americanum (Prickly-Ash) and Thuja and across the new-cut field of mixed hay, where there was one little Leopard Frog in the quickly drying hay.

FWS had seen one fly-by Danaus plexippus (Monarch Butterfly) on our way into the site (up near the farmhouse).

The river is about 100 metres wide here, and slow, and mid-channel, it is at least 6 feet deep, according to Chris.

Nick arrived later, and is waiting for us to get to land.

Fred found some live clams by "gunging" with the smelt net.

Schueler, Aleta Karstad Schueler, Orion Clark, Chris Stone, Nick Mulder. 2009/199/-, datasheet (datasheet) (event). nat.hist., wade, dipnetted, walk. WAYPT/Y 048, Tay Macroinvertebrate & water chemistry survey. This is the Golf Course Bridge, in Perth. There's a nice big Beaver lodge downstream of the bridge on the south side. Air 27 C on fencepost in shade.

DATASHEET SUMMARY: Land ownership is municipal right-of-way, with private land all around. The locality is based on global positioning (+/- 6 m). The diel period was midday. The site was in/on shallow valley.

The terrestrial vegetation was Soft Maple forest. Human impact on the site included bridge concretized and rebuilt since last visit, golf course back from water on S side, town on N. Site wetlands were permanent fringing riverine Beaver-influenced marsh. Dominant wetland plants were: Pontedaria, Typha angustifolia (Narrow-leaved Cattail). Development stage of Typha angustifolia (Narrow-leaved Cattail), was mature seedheads. Water at the site was permanent natural somewhat canalized river. Bottom vegetation is Myriophyllum or Coontail, and a fine, detritis-clogged aufwuchs-style algae. Frogbit and White Waterlilies, as well as a spatulate-bladed plant with a grass-blade like stem, growing right at the SE corner of the bridge where notes were taken.

Water level was high. The bottom was boulders & muck. Water quality was somewhat greenish. Water somewhat turbid, but turbidity increased markedly in turbidity at about 12h20. Spaces under rocks were clear of sediment. Water movement was medium LENGTH SAMPLED: 200 m (FWS) 50 m around bridge (others). Capture was by hand & dipnet.

Chris saw about six "normal-looking crayfish" and is trying to catch strange Smallmouth fry, Sunfish, Sucker fry about 10 cm, large pectoral fins. On the rocks that Chris overturned, there are two or three Catastomids just sitting there on the overturned rocks, just "munchin' away" on the under-rock aufwuchs.

Fred collected shells from a Beaver pile, no living clams. Damselflies mating, Spirodela round duckweed with a lot of reddish or brown individuals, floating sparsely against other plants. Lythrum salicaria (Purple Loosestrife), Jewelweed, and St Johnswort as well as Dogwood, among the traprock by the bridge abutment.

HABITAT: canal in town. 2009/198/k, visit () (event). natural history, wade, dipnetted. Tay Macroinvertebrate & water chemistry survey. Start time 12h45: Beckwith Street Bridge, swung open and not used because of need for repairs. Very turbid in main channel. 1-2 cm spots of foam floating down stream, evenly sprinkled in centre of the stream. Waypoint lost, so reconstructed from Google Maps.

Fred is collecting clam shells under the swung section of the de-commissioned wooden bridge, almost certainly a Muskrat shell pile. A lot of the "rocks" are slabs of concrete. He just turned a huge one, and is picking up a cluster of shells where it had been.

Vegetation in the canal is algae-coated Vallisneria. Nick returns from downstream, saying "it's the same crap downstream" - which is taken to mean similar conditions.

01:17:16 PM Suddenly we smell a perfume smell - Chris mentions it. Fred identifies it as Palmolive liquid detergent scent. It was only a pulse, lasting about five minutes, and now at 01:19:50 PM we can no longer smell it - Chris remembers later that this is a regular emanation of the Perth Soap Factory.

There have only been a couple of boats going by - the second one raising a considerable slosh. The turbidity may be at least partly due to the wakes, because we can't see into the water along shore at all after it has passed.

No live Unionids: perhaps they don't live in shallow water here because of the wakes of passing boats. Chris brought back a nice big Alasmidonta marginata (Elktoe) shell, fairly fresh, with lots of nice green rays and crisp crinkles.

We approach the river from the mowed lawns of the park, beside a pumping station enclosed in a chain link fence. This bank is across from the straight bank along the "Tow Path" road. The Tay looks like a canal here.

We are sitting at the Cockburn St. Outflow, Chris says "the number one storm sewer outflow in Perth" - not one of the two that will be mitigated, Just this morning Chris got the first confirmation of a victory for the Friends of the Tay - "the town of Perth is committed to mitigating any of the sewage outfalls into the Tay two are slated for improvement the North Wilson St cachement area is one of the top three. There are thirty. They estimate that after mitigation, they will reduce the total suspended solids by 80%. Unfortunately the potential for mitigation at this site is not high they have land, but the berm behind us is the main sewage trunk overflow. . . they have no flexibility and there would be a tremendous cost involved. However, they will put in a couple of minor 'swells' at the ends of this street here".

Nick says the water seems very warm here. Turbidity is high, but not as bad as the last place - about the same as at the Peter St. bridge. There is only Valliseneria here in the way of plants, and no emergent water plants due to the wakewash, except for a thin margin of Cattails in some spots along this bank, and a few Waterlilies. Not much other sign of life. There is a fair amount of bedrock outcropping, varying the water depth. There are areas of a few inches of muck depth, above rock or sand.

02:25:43 PM Chris has only found a few snails. No clams.

02:36:13 PM Nick has brought me two Elliptio shells and a snail.

02:36:58 PM Chris brought a live Zebra Mussel 22 mm that he found attached to the underside of a rock. Also two Caddisfly cases, also from the undersides of rocks He says that there was a tremendous Caddisfly hatch at the Craig Street Bridge last night.

02:44:14 PM Small inboard motor boat (about 14 footer) just passed, going at a clip of about 6-7 km, possibly the worst speed for wake size - it trailed a wake of at least 30 cm high, which almost sloshed to the top of the bank. Chris and I are appalled.

02:51:32 PM Fred has returned from downstream, having seen a great big female Orconectes virilis, around an island at WPT #52. He found a Muskrat "scrap-heap" and got some clams, including a Lampsilis radiata silliquoidea. He tried to catch another crayfish, but it got away. He is hearing Swifts. But not seeing them

The aquatic vegetation is much more diverse than the last place, and AKS made up a plant press synoptic - Myriophyllum type, ruffly pondweed type, Valliseneria with lovely tube-like flowers on long spiral stems, and a mossy weed from the rocks that is about 8 cm long and clotted with brown algae on all but its green growing tips - and the duckweed Spirodela. The opposite bank is grassy, with Sparganium along the water.

15:15 Chris has collected a large sample from a Muskrat pile in the water under a tree, containing Elliptio and Lampsilis (Lamp-Mussel) (2009/198/o).

15:35 Orion picked up a clam shell bearing a nice group of the flap-like alga, for me to take a PHOTO.

An Oriole makes its whistling peep call from one of the scattered Maples on the opposite bank.

439) Bathurst: Tay R/Co Road 6, Schoolhouse Bridge. (150m ard bridge), 31C/16 T, 44.82386N 76.38878W TIME: 1710-1850. AIR TEMP: 27, sunny, breezy. HABITAT: fast deep clear granite/boulder/gravel/muck river, oldfield/fencerow shores. OBSERVER: Frederick W. Schueler, Aleta Karstad Schueler. 2009/200/b, visit () (event). natural history, oil. painting from under bridge span, looking S & upstream. We parked where Jenn & Rory could find us, and walked down to the shade of the NE corner of the bridge to do a 1-hour oil painting. The roadside shoulders are seething with nymphal Grasshoppers.

Water is slightly higher than yesterday, as it's washing over low parts of the whole ledge on the north side of the span, whereas yesterday this was only happening at the upstream metre or so.

Aleta is painting upstream along a shore with emergents and Decodon, while the south shore below the bridge is a wall of chlorophyll: Tsuga among Tilia, with some Acer saccharum (Sugar Maple) and Acer rubrum (Red Maple), and some smaller trees along the water that I can't identify from across the river.

440) (same location) 2009/200/ba, Hyla versicolor (Tetraploid Gray Treefrog) (herp). several call, heard. sporadic calling through visit. 17h10: repeated calling from trees back from rdside

17h24: repeated calling from trees back from rdside

18h01: heard from down near river (NE corner of bridge)

18h20: short "bret-bret-bret-bret" calls heard from down near river. Are these territorial or first-year vocalizations?

18h42: calling repeatedly.

441) (same location) 2009/200/bb, Rana clamitans (Green Frog) (herp). 1/several call, heard, photo. sporadic single calls, big F on shore NE of bridge. . . . comes back to shore a few times, "as if trying to drive us away" -- but more likely unfond of current and Micropterus (Micropterus sp.) in main current.

442) (same location) 2009/200/bd, Micropterus dolomieui (Smallmouth Bass) (fish). 3 adult, seen. ca 30 cm TL, patrolling shallow water clear above bridge. There are also smaller ones in the main current, and smaller fish have been jumping out of the racing current below the bridge thruout our visit.

443) (same location) 2009/200/be, cf Sphex pennsylvanicus (not listed) (fish). 1+? mature, food, prey of predator, seen. ca 30 cm TL, patrolling shallow water clear above bridge. As we climbed down the steep sand/gravel bank under the edge of the pavement of the NE corner of the bridge, there was a big black wasp buzzing around. As we got down to the river, there was a dead female Katydid on the awash concrete footing ledge along the N side of the bridge. At 18h30 when what I at first took to be a Hummingbird buzzed over the river from the north shore, under the span. This creature had some of the green coloration expected in a Hummingbird, but it trailed long Katydid legs, suggesting that it was Sphex pennsylvanicus. This huge composite Insect buzzed around repeatedly under the bridge as if confused, bumping up against dark spots on the far wall of the bridge, and then circling around to come out of the east side of the span, and then dropping the Katydid in the water.

The wasp swooped down towards the dropped prey, and in turn was lept at by a 20 cm fish (these had been jumping out of the racing current below the bridge throughout our visit). I couldn't see if the fish got the wasp, but at 18h36 a wasp was again buzzing around above the Typha NE of the bridge, where we were sitting. I wonder if this was the same one, and if the Katydid I found on the ledge was the result of a similar previous confusion under the bridge.

444) (same location) 2009/200/bf, Tettigoniidae (Katydid) (entomological). 1 mature, specimen. on bridge abutment under bridge.

17h51: with a big tuft of greenery, and then a second trip with a linear-leaved load like a spray of antennae

18h09: a trip with broad leaves, like Nymphaea (White Waterlily).

It swims along the shore and then backs into a bush; is this a mother carrying food to young in a burrow?

There's a constant stream of cut-off macrophyte parts coming down the river in the main current.

We had Jennifer and Rory come out to enjoy Daminano with us and celebrate Rory's "brilliant" completion of his Medieval Comp Exam (we were alone since Antony had gone visiting) and they slept on a high loft platform perched on high cross-beams beneath the peak of the cathedral ceiling of the upper floor of the house.

We had a pleasant visit and supper, and heard sporadic calling by Hyla versicolor (Tetraploid Gray Treefrog) and Pseudacris crucifer (Spring Peeper), but didn't record times or temperatures. Then after dark we heard calling by a very distant cf Bubo virginianus (Great Horned Owl), distant Gavia immer (Common Loon), and also a nearby mysterious cruching growling mammalian sound. A few Lampyridae were blinking, and FWS watched one, near the pond, "warm up" by blinking repeatedly on the ground, and then go vertically into flight. A few Perseid meteors overhead before we went to bed.

HABITAT: shallow limestone bedrock/slab river through mixed woods & alvar-like barren flats. OBSERVER: Frederick W. Schueler, Aleta Karstad Schueler, Orion Clark, Chris Stone, Nick Mulder, George Hendry. 2009/204/-, datasheet (datasheet) (event). nat.hist., wade, dipnetted. WAYPT/Y 062, Tay Macroinvertebrate & water chemistry survey . . Susan Brandum's place: Arrival time approx 14:00.

DATASHEET SUMMARY: Land ownership is private. The locality is based on global positioning. The diel period was midafternoon. The sky was clear with bright sun. The wind was breeze Beaufort 4 Force. Weather for the past 48 hr was seasonally normal temperatures seasonally normal moisture. The site was in/on floodplain. Bedrock was exposed limestone. Upland substrate was bedrock over nearby areas. The terrestrial vegetation was parkland (40% wooded) and alvar-like barren flats. DOMINANT SPECIES: Sedum acre (Mossy Stonecrop) all over the limestone flats. Human impact on the site included lawn-chair recreation; the third of five mills at Port Elmsley was situated here, and remains of the dam can be seen upstream of the waypoint. There were no wetlands at the site, but Pontederia along some shores. Water at the site was permanent natural bedrock & slab-bed river. Water quality was clear. Spaces under rocks were very clear of sediment. Water movement was fast. Water level was high, but with streamside rocks exposed for the first time. NO:Eurycea under those that were turned (also no seepage along this shore). WIDTH: 25-30 m, LENGTH SAMPLED: 200 m, MAX. DEPTH: 50 cm, DEPTHS SAMPLED: 0-50 cm. Dominant aquatic plants were submerged black-disc algae. Otherwise rocks are bare. Capture was by hand dipnet. Cover checked included flat rocks.

14:20: Nick brought in a Caddis fly larva, its tube made out of gravel, rather than sand. In cracks in the rock bottom, there are deposits of little Sphaerids, two individuals are 4 mm and 5.5 mm. "Not much muck on the bottom - clears up very fast"

The river is about 20 - 30 m wide here, with riffles most of the way. Just about 20 m upstream of the step-like ledges at the waypoint, with shade of Alder and Buckthorn, the riffles begin, and Fred and Chris waded and gunged in still-surfaced water.

14:35: Chris says NO:Dreissena seen. Fast-moving Small-mouth Bass. Not a great number of clams. Lifted many rocks, saw no Crayfish. Several Caddisflies under rocks. No Muskrat piles. Too much current.

02:39:11 PM FWS came back from upstream, and said the Crayfish are small, and very adept at ducking down into the successive crevices of the piled slabs of rock. They don't get swept into the current and downstream, so he had a very low success rate for catching them.
