Station:  Grafton Pond (GRPNH)


Grafton Pond dam is located at the west end of the lake in Grafton, 
on the Enfield town line.

The following parameter is currently
being measured at this site:

Grafton Pond Stage (Lake Elevation)

Summer Opereations
Lake level is maintained at full pond. Full Pond level is equal to 
16.0 feet on the local gauge, or the top of the spillway at the dam.

Seasonal Fall Drawdown
At this time there is a two foot drawdown.
This is still under evaluation by DES. 
Drawdown levels could change in the future.

Spring Refill
Gates are used to limit outflow to fill pond after ice out, in Mid April.

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
