Acc. Number 2018-X:19 Specimen Remarks m, f, juveniles. Fixed in 10% buffered (dolomite) formalin ~1 month.
Collecting Event Remarks Water temp. = 20.5 C. All fishes were seined along the margin of a 90 m long wide spot in the creek below which the stream was dry for 40-50 m followed by pools and another shorter dry stretch. This wide spot was mostly 10-15 cm deep except along one shore where there were large slabs of concrete and twigs in water. This is where most of the fish were found. The largest and most abundant Cottus occured where the algae from one side approached the twigs on the other at the downstream end. Dragonfly naiads present and as in every station on this creek, crayfish have been abundant. Also caught Catostomus occidentalis, Cottus asper, and Oncorhynchus mykiss.
