Duchesne Valley Water Treatment Plant
The Duchesne Valley Water Treatment Plant
is located east of the Starvation Dam and distributes water to
customers through over 50 miles of pipeline.
This plant serves Myton, Duchesne City, East
Duchesne, and Johnson water. With a capacity of eight million gallons
a day, this plant treats water form Starvation Reservoir.
Starvation Reservoir is the water source for the plant. Strawberry
River is the major inflow to the reservoir, but water is diverted
from the Duchesne River, at times through Knight Diversion. Water
quality in both sources is very good with only seasonal exceedences
of water quality criteria. The watershed is large with very remote
areas.
A cooperative watershed management program was initiated in the
early 1990's to assess possible future impacts on the reservoir.
Impacts were largely due to recreation, sedimentation, and widespread
grazing. The major tributary streams are monitored
by the Utah Division of Water Quality.
