Cowlitz Wildlife Area
Kosmos Unit
The Kosmos unit is 750 acres on the east end of Riffe Lake. It is managed for black-tailed deer, bald eagles, and waterfowl, and riparian forest, riparian shrub and emergent wetland habitats in general. In addition to several large fields that are hayed by contractors to maintain forage values, there are ponds and forest/shrub corridors. Three perennial creeks that flow into this unit are managed for cavity-nesting species and salmonids. A proposed project to create a 40-acre impoundment will provide additional emergent wetland habitat to benefit dabbling ducks, amphibians, and other wildlife. Pen-reared pheasants are released for fall hunting. A hang-glider landing zone is located along the dirt shoreline of Riffe Lake.
