Lake has been measured by the California State Lands Commission, to be 328 Feet deep at it's deepest point -- just off the guard rail along Donner Pass Road. The Lake is just under 3 miles long and about 3/4 miles wide. High Water level is 5935.8 feet above Mean Sea Level (since Lake Tahoe's high water line is 6228' MSL, that dispels the myth that somehow the two lakes are connected). Donner Lake can reach a temperature of 76Â° during Summer.
