Box Canyon Creek Bull Trout Population
Overview
Box Canyon Creek originates in the Alpine Lakes Wilderness Area and flows into Kachess Lake from the northwest near its northern end. The reach accessible to migratory fish is about three miles downstream of the wilderness boundary and entirely within the Okanogan-Wenatchee National Forest. This reach is relatively short with an impassable waterfall (Peekaboo Falls) located at its upstream end approximately 1.5 miles above the reservoir. No significant tributaries enter the creek in the accessible reach. Complete dewatering at the mouth of Box Canyon Creek has been known to occur in late summer during dry years when streamflow is low and the reservoir level has dropped significantly due to irrigation demands.
Population Information
Population Distribution and Life History
The Box Canyon Creek population displays an adfluvial life history type. It is possible that a resident component exists as well although this has not been confirmed. The spawning area extends from Peekaboo Falls downstream, generally ending a short distance (~0.1 mile) above Kachess Lake. Juvenile rearing occurs in the entire 1.6-mile accessible reach. The lake provides FMO habitat for subadult and adult fish (MAP). Adult bull trout typically move into Box Canyon Creek in mid-July to mid-August, prior to spawning, and numerous fish migrate to and hold in the large pool directly below Peekaboo Falls. However, migration timing may be changing due to flow and temperature conditions during summer in Box Canyon Creek (15+ C). Cite evidence (peekaboo adult snorkels 2022-2025)
Natural Barriers limiting distribution
There is an impassable waterfall (Peekaboo Falls) at 47.375791, -121.258198 about 1.5 miles upstream of the reservoir.
