1989 Study:

50-year drought yield sufficient at present level of water use.

USGS Gages:

No data available

Developments since 1989:

Volunteer measurements of lake depth have shown that reservoir sedimentation has been minimal since the 1980s due to construction of grass waterways and buffer strips upstream. There are plans to double the capacity of the 2.23 mgd treatment plant in the next few years.
