Use the finished drawing from Problem P8–6 to complete this problem. Cut a profile along the stream. Determine the best location for a small dam and pond with a water level that keeps the pond inside the property line. Construct any needed profiles to show the height of the dam and the water line. Add the dam and pond to the map. The drawings submitted for this problem should include the map
and profiles and should provide enough information to fully describe the size and location of the dam and pond. What will be an ideal response?
