The U.S. National Weather Service’s April 1, 2010 forecast for volume of flow in the Similkameen River at Nighthawk, Washington, for April through July 2010 is 865,000 acre-feet. This forecast meets the criteria for a drought-year declaration for Osoyoos Lake as specified in Conditions 8a of the International Joint Commission Order of Approval dated December 9, 1982. Between April 1, 2010, and October 31, 2010, the State of Washington is required to maintain Osoyoos Lake at a level between a minimum of 910.5 feet USCGS (U.S. Coast and Geodetic Survey), and a maximum of 913.0 feet USCGS. This drought declaration will be rescinded before October 31 if hydrologic conditions change such that none of the drought criteria specified in Condition 8 continue to be met.
