anadromous populations occurring in the Puget Sound Basin and only resident fish occurring in the
Columbia River Basin (Brown, 1994). Populations west of the Cascade Mountains appear to be healthy and
stable while most populations East of the Cascade Mountains in the Columbia Basin are depressed
(Mongillo, 1993).
Bull trout are primarily piscivorous and prey heavily upon young salmonids and other fish. Lake dwelling
populations exist in many Washington lakes. Mature bull trout ascend tributary streams to spawn in the fall
months and display an ability to pass stream barriers that can block chinook and steelhead migration.
Po~ulations in the Vicinity of the Site
Bull trout have not been found in the Railroad Creek drainage.
