[edit] Some questions

Which is right? -- The dam concept involved pumping water into Grand Coulee, almost six hundred feet above the level of the Columbia River or Water is lifted 280 feet from Lake Roosevelt to feed the massive network. ?

Both, the lake is higher than the river. --Duk 09:24, 28 December 2006 (UTC)

During the last ice age glaciers ... diverted the Columbia River through what became the Grand Coulee. Grooves and striations created by glaciers are still visible in the underlying granite bedrock of the area (where the Basalt layers are thin). Ice age glaciers also created Lake Missoula, in what is now Montana. The glacier dam periodically burst creating the Missoula Floods, which gave way to a two thousand foot (600 m) head of water. These floods scoured the Columbia Basin and the Grand Coulee in particular. Unique erosion features, called channeled scablands, are attributed to these amazing floods. ... Thousands of years of erosion by the Columbia River gave final shape to the basin. The Columbia channel no longer flows through the Grand Coulee

I thought Grand Coulee was made by the Missoula Floods, not glaciers or a former river course. Can we get a reference for this?

Glaciers left their mark all over the grand coulee area, as did the misoula floods. But you are right, wording can be improved and references should be added. --Duk 09:24, 28 December 2006 (UTC)

Electricity is now shipped to Canada and as far south as San Diego. ...reference for this?
