Northwood Lake dam is located at the west end of the lake in Epsom.

The following parameter is currently
being measured at this site:

Northwood Lake Stage (Lake Elevation)


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


Seasonal Fall Drawdown
After Columbus Day the lake is slowly lowered to a target 
drawdown of six feet below full pond. The usual drawdown is five to 
five and a half feet below full pond. 
This is done by the removal of stoplogs at the dam.


Spring Refill
Lake is filled just after ice out or by May 1st. This is done by 
replacing the stoplogs at the dam.


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.
