Station: Great East Lake (Wakefield)

Great East Lake dam is located at the south/east end of the lake on the 
NH/ME border in Wakefield.

The following parameter is currently
being measured at this site:

Great East Lake Stage (Lake Elevation)
Precipitation,air temperature and humidity.
Note: Precipitation is not recorded in the winter months from
October to April.

Summer Operations
Lake level is maintained at full pond. Full pond is equal to 
the top of the spillway elevation at the dam.

Seasonal Fall Drawdown
The lake level is gradually lowered by operations of the gate at the dam. 
These operations start at the begining of October of every year. 
The lake is lowered to three feet below full pond level.

Spring Refill
Lake is refilled during spring runoff, and full pond is achieved 
after ice out.

Note: Water levels generally fluctuate in response to precipitation,
snowmelt, drought or other meteorological conditions. Target water levels 
are maintained by the adjustment of flows at the dam in response 
to these conditions.
