A gravelly sand channel slopes away from a reservoir, through the reservoir rim, to an adjacent drainage area. The channel slopes at a gradient of 23 m (75 ft) vertically to 30.5 m (100 ft) horizontally. In cross section the channel is 1.8 m (6 ft) thick and 4.6 m (15 ft) wide. The channel intersects the adjacent drainage area at a horizontal distance of 152.4 m (500 ft) from the reservoir. a. At minimum pool elevation in the reservoir...
