The Government is flooding the Grand Canyon in hopes of saving the fish. The blue head sucker and specled dace are still swimming but the native humpback chub and razor sucker are endangered. Ever since the Glen Canyon Dam in Arizona was built in the late 50's,early 60's, scientists have noticed a huge decline in sandbars. The dam regulates the flow of the Colorado River through the Canyon. The big problem is, the Grand Canyon doesn't receive the natural flooding it needs to keep the sediments flowing.The sand that the Grand Canyon would naturally receive is now being trapped in the dam. Silt is also building up in the areas where the fish live. This is one flood I'd love to see!
