Station:  Angle Pond (ANPNH)


Angle Pond dam is located at the south/east end of the lake in Sandown.
The following parameter is currently
being measured at this site:

Angle Pond Stage (Lake Elevation)

Summer Operations
Water level is maintained at full pond. Full pond equals 
top of spillway at the dam.

Seasonal Fall Drawdown
There is a short drawdown season; the lake level is dropped 
by two feet from Columbus day to December 1st.
Then all stoplogs are put back in the dam.

Spring Refill
Water level rises gradually over the winter months after stoplogs
are replaced. 
Full pond is usually achieved just before ice out on pond.

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
little or no review. Inaccuracies in the data may be present
because of instrument malfunctions or physical changes at the
measurement site, including backwater effects due to ice formation.
Although the data presented herein is intended to be an accurate
representation of actual conditions, it is presented for
informational purposes only and the user is cautioned to use it at
