Detailed SR Function Description
Figure 11B. Snorkel observations of adult cutthroat presence within pools of tributaries to the main and South Umpqua Basin, author’s data.
Parr of all salmonid species strongly avoided areas with depths <0.2 m, and steelhead and cutthroat parr showed increasing densities as unit depths increased up to at least 1 m.
Curve is converted from ft to m. Scaled from the original curve so that the highest upper limit value equals to 100% (original value was 47.2%).
