PRICE - SAN RAFAEL RIVERS UNIT - UTAH

The Price and San Rafael Rivers are located in east-central
Utah and provide tributary flows to the Green and Colorado Rivers.
The drainage areas contain 1,900 and 1,600 square miles for the
Price and San Rafael Rivers, respectively.

The salinity problem from thcze basins results from the
irrigated lands, which are located on the salt producing shale
formations in the upper portions of the drainages. The salinity
concentrations average 3,500 mg/L and 4,000 mg/L for the Price
and San Rafael Rivers, respectively. The combined salt load
from the rivers is 430,000 tons per year. It is estimated that
approximately 180,000 tons could be removed from an evaporative
system. This would reduce the salinity concentration at Imperial
Darn by 11 or 12 mg/L, but would also deplete the flows by 60,000
acre-feet.

A professional services contract was awarded in September, 1981,
to conduct investigations and' identify alternative plans capable of
reducing the salinity in the river systems. A planning team and
public involvement program are being organized to assist the con-
tractor in selecting a recommended plan by September, 1983. The
feasibility study is scheduled for completion in December, 1986.
