About this gauge's record

USACE's continuous elevation record for this project begins in 2013 (2 tracked series for this project).

The dam behind Jordanelle Dam & Reservoir

Jordanelle Dam & Reservoir is held back by Jordanelle Dam (also recorded as Jordanelle Reservoir) , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 391 ft high and running 3,820 ft along its crest , built across PROVO in Wasatch County , near HEBER . It was completed in 1993 , and is owned by DEPARTMENT OF THE INTERIOR (a federal owner) , to a design credited to BUREAU OF RECLAMATION.

Its recorded primary purpose is water supply — delivering water to its customers comes first, so drawdown here follows demand as much as it follows rainfall .

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 41 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.

NID records a maximum storage of 363,354 acre-ft against a normal storage of 0 acre-ft. Its maximum discharge capacity is 3,800 cubic feet per second.
