Overview 

Experimental long-range streamflow forecasts for the Columbia River produced at the University of Washington by the Center for Science in the Earth System and the Department of Civil and Environmental Engineering have been demonstrated to have economic value to water resources management in the Pacific Northwest, particularly in the context of hydropower planning and marketing. Simulated benefits to spot-market energy revenues in the Columbia basin associated with the use of ENSO-based, long-range streamflow forecasts are on the order of $150 million per year (Hamlet and Lettenmaier, 2002).
