System Description
Greenfield Lake is the main regular source. Portable pumps can extract water from Coles Lake, a pond upstream, during emergencies, although this source has never been used. Water is piped directly from the lake to the system's 2.5 mgd treatment plant at 350 gpm.

Developments since 1989:
This community had to shut off pools and car washes and ban lawn and garden watering due to shortages from a water deficit that began during the 2005 drought. Bulk water sales were prohibited from May 2006 to January 2007. The community is working on an emergency connection with the Greene RWD.
Note: *Coles Lake never has been used as an emergency source. Its capacity estimate is based upon a rough estimate of its surface area (7 ac) and average depth (7 ft).
