Did You Know?
Lake Roosevelt is the primary flood control reservoir on the Columbia River. The lake level can rise up to 4 feet per day in spring and drop 1 foot per day in summer. When shoreline camping, find out what the lake level is and don't put a tent close to the water unless you want a chilly surprise.
