Driscoll Islands Unit
The Driscoll Islands unit is about 350 acres (including a 2007 acquisition on Eyhott Island to the south) of mostly riparian and wetland habitat located about one mile south of Oroville, at the confluence of the Similkameen and Okanogan rivers. During high water years, much of the island, at just 280 feet in elevation, is flooded. The primary goal for purchase in 1974 was to provide goose nesting and foraging habitat. Grazing was once used to improve forage, but has been discontinued since the goose population has returned to healthy numbers. A sharecrop agreement is used on agricultural lands for hay and grain production to enhance forage for upland game birds. River channels surrounding Driscoll Island provide migration and spawning habitat for steelhead, fall Chinook salmon and Osoyoos Sockeye salmon. The unit supports a small deer population, a variety of waterfowl, reptiles and amphibians and other wildlife. Access to Driscoll Island for fishing, hunting and wildlife viewing is by a ford across the Okanogan River during low flows in the summer and fall.

    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.
