About this gauge's record
This site's drainage basin covers approximately 64 sq mi of contributing watershed.
The dam behind Lake Sherburne at Sherburne
Lake Sherburne at Sherburne is held back by Lake Sherburne Dam (also recorded as Lake Sherburne) , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 109 ft high and running 1,086 ft along its crest , built across SWIFTCURRENT CREEK in Glacier County , near BABB . It was completed in 1919 and modified in 1982H;1982S , and is owned by BUREAU OF RECLAMATION (a federal owner) .
Its recorded primary purpose is irrigation — the pool is drawn down across the growing season to serve water rights downstream, then refilled over winter .
Its spillway is ungated: once the pool reaches the crest, water leaves on its own and the operator cannot hold it back. The spillway opening is 96 ft wide.
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 2,163 acres. NID records a maximum storage of 110,679 acre-ft against a normal storage of 67,854 acre-ft. Its maximum discharge capacity is 2,260 cubic feet per second.
