Station:  Squam Lake (SQLNH)

Full Lake = 12.5 ft. Local = 562.50 ft. above sea level


This station is located on the abutment of the US route 3/NH route
25 bridge that crosses over the channel separating Squam and Little
Squam Lakes. The following parameter is currently being measured at
this station:

Squam Lake Stage (Lake Elevation)

Spring Refill
Lake is filled between early May and early June to a level of approximately
12.5 feet on the gage. 

Summer Operations
Lake level is managed by bringing it up to full or 12.5 on the gage, then
adjusting releases at the dam to try to keep the lake as near to 12.5 as
possible through Columbus Day.

Seasonal Fall Drawdown
After Columbus Day the lake is slowly lowered to a target drawdown of 2.5
to 3 feet below full pond to allow shorefront maintenance to occur and to
prepare for spring runoff.  The drawdown is accomplished by the operation
of hydroelectric turbines and flood gates at the dam.

Note: Water levels generally fluctuate in response to precipitation,
snowmelt,drought or other meteorological conditions. Target water levels 
are mantained 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).
