Station:  Deering Reservoir (DERNH)




Deering Reservoir dam is located at the north/west end of 
the lake in Deering.

The following parameter is currently
being measured at this site:

Deering Lake Stage (Lake Elevation)

Summer Operations
Water level is maintained at full pond. Full pond level is equal to 
the top of the flashboards at the dam.

Seasonal Fall Drawdown
After Columbus Day the reservoir level is lowered by one 
foot untill November 1st. 
Then the lake is lowered three more feet to 
achieve a four foot drawdown.

Spring Refill
Stoplogs are put back in the dam through spring runoff to 
reach full pond when ice is out.

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
