North Dam, Grand Coulee

North Dam is an earth-fill embankment dam near the town of Grand Coulee in Grant County, Washington, United States. Construction of the dam began in 1946 and it was completed in 1951. Along with Dry Falls Dam about 22 mi to the southeast, North Dam creates the reservoir Banks Lake within the ancient Grand Coulee riverbed. The lake serves as the equalizer reservoir of the Columbia Basin Project. Near the North Dam's left abutment is the entrance to the feeder canal of the project. The canal serves to either deliver water to the Pump-generating plant at Grand Coulee Dam or return water to Banks Lake from the same pumped-storage plant. ()
