Collecting Event Remarks Water temp. = 21 C. No males in reproductive coloration, only 1 adult stickleback seined. All sticklebacks collected, many Cottus thrown back. This sample was made in the upper 100 m of the estuary, below the most downstream riffle. Most of the sticklebacks came from open water, emergent grasses, on beneath recumbent tree limbs. The estuary in this area is flat bottomed with only 1 marginal pothole against a cliff. This pothole contained only Cottus including the single large specimen seined. Platichthys also came from this hole. Dragonfly larvae absent. Also caught Cottus asper, Oncorhynchus mykiss, Leptocottus armatus, and Platichtyhus stellatus.
