About this gauge's record

This site's drainage basin covers approximately 67 sq mi of contributing watershed.

The dam behind Wrightsville Detention Reservoir

Wrightsville Detention Reservoir is held back by Wrightsville , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 115 ft high and running 1,525 ft along its crest , built across NORTH BRANCH WINOOSKI RIVER in Washington County , near MIDDLESEX . It was completed in 1935 , and is owned by STATE OF VERMONT - DEC (a state owner) , to a design credited to USACE.

Its recorded primary purpose is flood risk reduction — the pool is drawn down between storms so there is empty space waiting for the next flood, which is why this level can fall in dry weather and climb sharply after rain . It also serves flood risk reduction;recreation;hydroelectric.

It is founded on rock;soil, with a earth core.

NID classes it high hazard potential. That describes what a failure would cost downstream — loss of life would be expected — and says nothing about how likely a failure is, or what condition the dam is in. Its most recent condition assessment was fair: sound under normal loading, though a rare or extreme event could expose a deficiency.

At its normal pool the reservoir covers about 190 acres. NID records a maximum storage of 36,000 acre-ft against a normal storage of 0 acre-ft.
