Skagit Headquarters Wildlife Area Unit
The Skagit Headquarters Unit — also known as Wiley Slough — is tidal marsh (estuary) on Fir Island, west of and adjacent to Freshwater Slough. The unit is predominantly vegetated by cattail and sedge and used extensively by waterfowl and other waterbirds, shorebirds, raptors, and passerines.
Recreation opportunities include bird watching, waterfowl hunting, fishing, dog walking, photography, and bird watching.
The Skagit Headquarters Unit was acquired by WDFW in the 1950's to provide agricultural enhancements for wintering waterfowl and increased hunting opportunity. With the Endangered Species Act listing of many salmon species including Puget Sound Chinook, habitat management has since shifted to restore estuary habitat while continuing to provide access for hunting and wildlife watching.
A popular boat launch on Freshwater Slough provides access to the Skagit Estuary and Skagit Bay, Island Unit, and nearby waterways. Boaters and kayakers should check tide charts as the ramp can be difficult to use in low water, and strong currents may develop during outgoing tides. Kayakers may also access the marsh from a hand launch site near the parking area.
The Skagit Headquarters Unit is located at the south end of Fir Island in Skagit County, adjacent to the South Fork of the Skagit River and Skagit Bay. The unit is accessed by turning south from Fir Island Road on to Wylie Road, then following Wylie Road until it ends at the unit entrance road.
The Headquarters (Skagit) Unit is located on Fir Island, west of and adjacent to Freshwater Slough. Adjacent uplands are private lands that were diked and drained at the turn of the 20th century for agricultural production, mainly cereal grains, vegetables, and dairy.
This unit is part of the Skagit Wildlife Area.
