Sunset Lake dam is located at the south end of the lake in Alton.

The following parameter is currently
being measured at this site:

Sunset Lake Stage (Lake Elevation),precipitation, air and lake temperature.
Note: Precipitation is not recorded in the winter months from October to 

Summer Operations
Lake level is maintained at full pond. Full pond is equal 
to 0.0 on local gauge at the dam, or top of spillway.

Seasonal Fall Drawdown
After Columbus Day dam gates are opened to allow for a seven foot 
drawdown from full pond level.

Spring Refill
Dam gates are closed to refill lake after runoff from snowmelt 
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.

This meteorological station is operated and maintained by
the New Hampshire Department of Environmental Services (DES).
