Grand Coulee Dam and completion. Creation of the reservoir forced the relocation of over 3,000 people, including Native Americans whose ancestral lands were partially flooded. While the dam does not contain fish passage, neither does the next downstream dam, Chief Joseph Dam. This means no salmon reach the Grand Coulee Dam. The second large dam downstream, Rocky Reach Dam, has an intricate system of fish ladders to accommodate yearly salmon spawning and migration. The Grand Coulee is an ancient river bed on the Columbia Plateau created during the Pliocene Epoch (Calabrian) by retreating glaciers and floods. Originally, geologists believed a glacier that diverted
Grand River (Michigan) stampede, as millions of logs flowed uncontrolled down the river and became trapped in bends or against bridges. The result was a logjam of incredible proportions that clogged the river for 47 miles (10 million Feet of logs trapped in Lowell, 95 million Feet of logs trapped in the "Big Bend" northeast of Grand Rapids, 80 million Feet of logs trapped in Ottawa County). Grand River Avenue (or Grand River Road) was built early in the settlement of Michigan and runs from the head of navigation on the Grand to downtown Detroit. It formed an important part of an early
