Station:  Souhegan 28 Flood Control (SOU28)

Normal Pool = 0.00 ft. Local = 831.00 ft. above sea level






Souhegan Flood Control Dam 28 is located on Old Temple Road in Lyndeborough,
approximately 5 miles northwest of Wilton Center on Rt 31.

The following parameters are currently being measured at this site:

Souhegan 28 Impoundment Stage (Lake Elevation)
Air Temperature

Souhegan Flood Control Dam 28 is designed to maintain a normal pool level and release excess water 
without operations. Normally the pond drain line gate is closed.  The normal level is maintained by 
the low stage orifice openings.  The principal spillway riser and reservoir storage is designed to retard 
runoff from up to a 100 yr storm without flow occurring in the auxiliary spillway.

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).
Most data relayed by satellite or other telemetry have received
