Convert depth and area to volume. Depth of water = 6” = ½ ft. Area = 100 acres. Volume = depth x area = ½ ft x 100 ac = 50 ac-ft. 2. Convert cfs to gpm. gpm (gallons per min) = cfs (ft3/s) x 450. 1 ft3 = 7.5 gal, 1 min = 60 s. 3. Find total discharge from depth, width, velocity measurements. Discharge = Velocity x Area. Avg depth = total area / total width ................
