With Lake Roosevelt about 4 feet from being full, the Bureau of Reclamation expects the lake to rise starting July 3 by up to a half foot each day through the weekend.
Filling the lake lifts accumulated debris off the shores and into the water where it can be dangerous to boaters.
The Bureau of Reclamation is advising people camping along the Lake Roosevelt shoreline over the July 4 weekend to be aware of potential dangers that could exist due to rapidly rising lake levels.
“When camping along the shoreline, it is recommended that tents and other belongings be kept well away from the water’s edge,” said Public Affairs Officer Lynne Brougher. “Although the lake is a popular vacation spot, it is also a working reservoir that supplies water for hydroelectric facilities at Grand Coulee Dam which can result in rapid fluctuations.”
Brougher says campsites that are too close to the water’s edge could potentially become flooded and boats that are not properly anchored or secured could drift out into the lake and become a safety hazard.
Reclamation must adhere to the court-ordered 2008/2010 FCRPS Biological Opinion requiring the lake to be at the full pool elevation of 1,290 feet above sea level between late June and early July. It was at 1,286 feet above sea level Tuesday evening.
