Columbia Basin Wildlife Area Winchester Reservoir Unit
The Winchester Reservoir unit is 930 acres of land and 1,020 acres of water just north of Interstate 90 east of the town of George. The lake is actually a wide spot in the Winchester Wasteway, with an average depth of about six feet. The surrounding landscape is relatively flat with the lake in a natural low area. Most of the lake is surrounded by cattail and bulrush marsh. The uplands are a mix of tall wheatgrass or intermediate wheatgrass with big sage/bluebunch wheatgrass in some areas. Waterfowl and shorebirds dominate. County roads provide public access to the parking areas and gravel boat launches on the south and upper east sides of the lake. About 20 acres are leased for farming.
