The survey site was busy with kayakers coming back to shore from evening paddles. A few dragonflies flying low over the water, and swallows flying overhead and around the bridge pylons, appeared to be tree swallows but too far away to confirm for sure. Saw a caterpillar on a tree beside the boat launch that is likely a type of tussock moth. Heard red squirrel calls in the trees. Saw 3-4 green frogs and 2 very large American bullfrogs, heard others a dozen metres or so upriver. Saw cyprinid fishes and a sunfish, water lillies, a dead crayfish with claws removed that is likely a rusty crayfish due to the markings on its carapace. Also found large shells from native mussel species, likely Eastern Elliptio based on iNaturalist suggested id and shell shape.
