Range and Identity
Cottus tenuis is recorded from the upper Klamath drainage, including Upper Klamath Lake and waters upstream. This is a more limited range than the full Klamath River system extending toward the coast. Nearby downstream or neighboring-basin records need separate identification evidence.
Habitat and Behavior
The fish occurs along lake shores over mud, sand and gravel, and in riffles, runs and pools of creeks and small to medium rivers. These settings span both standing and flowing water. A stream-only description would therefore omit part of the documented habitat.
Food and Life History
The reported maximum is nine centimeters total length, with seven centimeters as a common reference. An independent maximum weight and detailed diet or reproductive account are not established in the retrieved summary. The available evidence is strongest on range and habitat.
Field Note
Include whether the observation came from a lake shore or a stream, along with the substrate. Those details capture the documented habitat breadth without expanding the species’ restricted geographic range.
