Station:  Milton 3 Ponds (SFMNH)

Full Lake = 15.25 ft. Local = 413.87 ft. above sea level







This station is located at the Milton 3-Ponds Dam, which is located at the
southern end of the lake in Milton.  The following parameters are currently
being measured at this station:

Milton 3-Ponds Stage (Lake Elevation)
Salmon Falls River Stage / Flow
Air Temperature

Summer Operations
The lake level is managed by bringing it up to full summer recreation level by
June 1st.  Summer level corresponds to an elevation of 413.87 m.s.l. or 15.25
on the staff gage located at the dam's right abutment.  Over the course of the
summer months the pond tends to ebb, so that by Columbus Day the level is
between 6 and 12 inches lower.  

Seasonal Fall Drawdown
After Columbus Day the lake is slowly lowered to a target drawdown of 12.0 on
the gage, or about 3.25 feet below the June 1st target level, to allow
shorefront maintenance to occur and to prepare for spring runoff.  The drawdown
is accomplished by operating the dam's floodgates or spillway crest gate.

Spring Refill
The lake is raised to its summer recreation level between mid late April and
early June.  

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).
