Big Sandy Reservoir Enlargement Meeting
6 p.m., Nov. 7, Farson

The Bureau of Reclamation (BOR) has released a draft environmental assessment (EA) of the Big Sandy Enlargement Project.

The Big Sandy Reservoir, located about 10 miles north of Farson in both Sublette and Sweetwater counties, provides storage for irrigation, flood control, and recreation.

The Wyoming Water Development Commission is interested in increasing the storage capacity of the reservoir by raising the spillway crest by five feet, increasing total storage capacity (by 13,600 acre-feet) to 52,300 acre-feet. A toe drain and filter trench would be installed along the left abutment of the dam, a filter diaphragm would be installed around the outlet works, a cement-bentonite cutoff wall would be constructed through the crest of the dike, and since raising the reservoir would increase the water height on the existing dikes that are already experiencing erosion, additional riprap would be required. In addition, the project would replace the Big Sandy Feeder Canal headworks and six concrete drop structures.

A public meeting on the proposal will be held Nov. 7 at 6 p.m. in the Eden Valley Community Center in Farson.

Public comments on the proposal are due by Dec. 6th.
