The San Juan Water Conservancy District is planning a project to expand Dry Wash Reservoir, which is approximately 12 miles northwest of Blanding in the Manti La Sal National Forest.

The project will raise the height of the dam by 18 feet, increasing the capacity of the reservoir from 185 to 500 acre-feet of water.

The project would nearly double the surface area of the reservoir. It also includes 5,000 feet of buried pipeline to the Blanding culinary water line.

The reservoir is currently maintained by Dry Wash Irrigation Company and is used primarily for irrigation. The City of Blanding can use the water for culinary purposes in periods of drought.

It is estimated that up to 50 percent of the water is lost when is transported in the natural drainage channel below the reservoir. The pipeline will help significantly reduce the loss of water.

The new reservoir would have a 100 acre-feet conservation pool.

The project awaits Forest Service approval. It is hoped that construction can begin in April, 2014, with a six-month construction phase.
