    "descript": "Lake Mohave is one of several multi-purpose reservoirs that have been constructed on the Colorado River.  The lake was formed upon completion of the Davis Dam in 1953. No mapping of the floor of the lake had been conducted since completion of the Davis Dam. The U.S. Geological Survey, in cooperation with researchers form the University of Nevada Las Vegas, completed a geophysical survey of this lake in April 2002.  The survey included collection of sidescan sonar imagery of nearly the entire lake floor, and high-resolution seismic-reflection profiles along widely spaced lines throughout the lake.  The detailed mapping of the lake floor was used to determine the amount of sediment that had accumulated in the lake since impoundment, its distribution, and the processes of deposition.",
