PRECIPITATION ON THE LAKE

The average annual precipitation on the lake has been estimated for this report at 36 inches. The infalling volume in a season depends not only upon the precipitation but upon the area of the lake at the time when it falls; the average volume is probably between 6,000 and 10,000 acre-feet per year, or 5 to 9 percent of the average annual water supply.
