Several species of fish can be found in the park. Carp live in the Mill Pond. Longnose dace, speckled dace, and redside shiners swim in Mill Creek and Doan Creek. There are also steelhead and bull trout.
One of the goals of the Doan Creek restoration project is to provide suitable habitat for steelhead to reproduce.
