About this gauge's record
USACE's continuous elevation record for this project begins in 1984 (2 tracked series for this project).
The dam behind Jennings Randolph Lake
Jennings Randolph Lake is held back by Jennings Randolph Dam (also recorded as Jennings Randolph Lake; Bloomington Dam) , a rockfill embankment — quarried rock placed in compacted layers around a sealing core , standing 296 ft high and running 2,130 ft along its crest , built across NORTH BRANCH POTOMAC RIVER in Mineral County , near BARNUM . It was completed in 1981 , and is owned by USACE - Baltimore District (a federal owner) , to a design credited to CENAB.
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;other;recreation;water supply.
It is founded on rock, with a earth core. Its spillway is gated, so the operator can hold the pool above the spillway crest and meter what leaves. The spillway opening is 242 ft wide. Its outlet works use slide (sluice gate)0;tainter (radial)0;valve0.
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.
At its normal pool the reservoir covers about 965 acres. NID records a maximum storage of 130,900 acre-ft against a normal storage of 94,700 acre-ft. Its maximum discharge capacity is 193,000 cubic feet per second.
