Driscoll-Eyhott Island Unit

The Driscoll-Eyhott Island unit consists of about 325 acres of mostly riparian and wetland habitat located about one mile south of Oroville, at the confluence of the Similkameen and Okanogan rivers. Due to its low elevation (920 feet), the unit experiences moderate flooding during high water events in spring and early summer. The Washington Department of Fish and Wildlife (WDFW) purchased Driscoll Island in 1974 and added Eyhott Island to the unit in 2007.

When the unit was initially established, a primary management goal was to provide goose nesting and foraging habitat. Grazing was once used to improve goose forage, but was discontinued since Canada goose populations have returned to healthy numbers. The unit is still used for agricultural purposes. Hay and grain production enhances forage for upland game birds and provides cover for a variety of species.

River channels surrounding Driscoll Island provide migration and spawning habitat for steelhead, fall chinook salmon and Osoyoos sockeye salmon. The unit supports a small mule and white-tail deer population as well as a variety of songbird, waterfowl, reptile and amphibian species. Hunting, fishing, and wildlife viewing are all popular activities on the island. However, access to Driscoll and Eyhott Islands is only possible by fording across the Okanogan River during low flows. One could also access the unit by floating the Okanogan and Similkameen Rivers from upstream using a number of water access points.

    Unique Features
    Access to these islands is by wading during low water (July 15 to April 15) or by boat during high water (April 15 to July 15). There are no developed visitor or recreational facilities on Driscoll-Eyhott Island Wildlife Area. Sometimes bighorn sheep may be visible on the rock bluffs and cliffs across SR 97 from Driscoll and/or Eyhott Islands. Salmon can be seen in the Similkameen River channel during fall spawning season from the northwest shoreline of Driscoll Island. It is also a popular place for shore fishermen to fish for steelhead.
