Reservoir contents figures represent total storage, of
which 1,780 million gallons are dead storage. Total contents at
spillway level (302.4 feet) is 29,630 million gallons.
Occasionally the reservoir levels appear to be several tenths of
a foot too low due to possible drawdown caused by use of water
supply intakes at certain levels.
