About this gauge's record

USACE's continuous elevation record for this project begins in 2009 (2 tracked series for this project).

The dam behind Platoro Reservoir

Platoro Reservoir is held back by Platoro Dam (also recorded as Platoro Reservoir) , an earthfill embankment, holding the pool back by sheer mass and an impervious core rather than by the strength of concrete , standing 165 ft high and running 885 ft along its crest , built across CONEJOS RIVER in Conejos County , near PLATORO . It was completed in 1951 , and is owned by BUREAU OF RECLAMATION (a federal owner) , to a design credited to BUREAU OF RECLAMATION.

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;irrigation;fish and wildlife pond;recreation.

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 50 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 1,000 acres. NID records a maximum storage of 73,317 acre-ft against a normal storage of 53,506 acre-ft. Its maximum discharge capacity is 3,259 cubic feet per second. It is regulated by DWR.
