Station: Suncook Lake (Barnstead)

Suncook Lake dam is located at the south end of Lower Suncook Lake
in Barnstead.

The following parameter is currently
being measured at this site:

Suncook Lake Stage (Lake Elevation)

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

Seasonal Fall Drawdown
Drawdown begins on October 1st. Full drawdown is reached by 
Columbus Day in most years. This is done by opening the gates at the dam. 
Note: The water level at the dam is two to three feet lower than the 
lake level at the Narrows Bridge (between upper and lower Suncook Lakes)
gauge during winter operations

Spring Refill
Lake is refilled after spring runoff season ends and 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.
