Sunapee Lake Dam is located at the western end of at Sunapee Harbor,
approximately 1/4 mile east of the intersection of NH routes 11 and 103.

The following parameters are currently being measured at this site:

Sunapee Lake Stage (Lake Elevation)
Precipitation
Air Temperature

Summer Operations
The lake level is maintained as close to the full summer recreation level as
possible, as meteorological conditions and minimum flow requirements allow.
Full summer recreation level is 10.5 on the gage at Sunapee Harbor, which
corresponds to an elevation of 1093.15.

Seasonal Fall Drawdown
Drawdown begins on or near Columbus Day.  The lake is drawn down 2.5 feet
(elev. 1090.65) below the summer recreation level, and full drawdown is 
generally reached by February or March in most years. The drawdown is
accomplished by opening the gates at the dam.

Spring Refill
Lake is refilled to the full summer recreation level between March and June
1st as the snowpack melts and spring rains occur.   


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.
