This refuge encompasses over 11,000 acres with both lake and river units. The Lake Lowell Unit is a great birding spot with over 200 recorded species. Spectacular concentrations of birds can be seen on the lake during peak migration periods. Shorebirds occur in large numbers in August when low water levels expose mudflats. Waterfowl occur in large numbers in fall and winter. The lake is closed to boating October 1 through April 14. The Snake River Islands Unit contains about 1200 acres on 104 islands from the Canyon-Ada County line in Idaho to Farewell Bend in Oregon. The islands are closed to public access from February through June 15 (a few islands with colony-nesting birds through June 30) to protect nesting habitat.
