Grand Coulee Dam "The Power of Water"
Creating the irrigation program was as complicated as developing the dam. A massive pumping station was built to lift water 280 feet up into Banks Lake. From there, a network of more than 300 miles of canals and more than 3,000 miles of irrigation ditches provided water to an area twice the size of Delaware.
Average rainfall in eastern Washington is less than nine inches a year.
