Comments:
-some spawning potential upstream of culvert - good gravel limited by low flows
-site may be one of the few potential areas of spawning habitat which exist in the immediate vicinity of No Name Lake. However, no 0+ RB were observed at the time of this survey (late May) or captured during mid September in 1997.
