- Crescent Lake Wildlife Area Unit (wdfw.wa.gov)
The Crescent Lake Unit consists of forest, sloughs, and farm fields at the confluence of the Skykomish and Snoqualmie rivers. This unit is a popular pheasant and waterfowl hunting site in the fall and winter; other recreation opportunities include fishing, and bird dog training in designated areas. A network of trails wind through the forest and fields to provide areas for hiking and nature observation, plus a 200-foot long footbridge built across the lake in 1978 completes the loop.
