James and Company in 1991.  The Dam is of earthen construction with a maximum height of 93 feet and a length of 4,850 feet.  At normal conservation pool levels (2,200 feet above mean sea level), it has a surface area of 1,463 acres and a capacity of 27,266 acre-feet.  It is estimated that it is capable of evaporating up to an average of 7.0 million gallons per day.  It drains an area of 15.3 square miles.
