Bear River Development
In 1991, the Utah Legislature passed the Bear River Development Act, [Utah Code 73-26], which authorizes and directs the Division of Water Resources to “…develop the surface waters of the Bear River and its tributaries through the planning and construction of reservoirs and associated facilities…”
Planning and studies for the development or storage of the Bear River have been ongoing for several decades. The Division has been working with Bowen Collins & Associates to update and refine the findings of the 2014 Pipeline Concept Report for a conceptual Bear River Development (BRD) system. The feasibility report is now complete (see four files below) and includes conceptual level planning for a BRD system that would include reservoirs, pipelines, pump stations and other facilities. Multiple options of reservoirs and pipeline corridors have been studied and cost estimates have been updated.

Who will the project benefit?
The Bear River Development is designed to provide additional water supplies for northern Utah residents.
When will it be needed?
Original projections estimated the water would be needed in 2015. However, current estimates place the demand between 2045 and 2050. This could change based on conservation progress and population growth. Although the water is not needed for many years, the division has begun corridor preservation for a large-diameter pipeline through Box Elder County. As development has increased, the division has seen the need to preserve a corridor to reduce future impacts to the surrounding communities. The division has a Memorandum of Agreement with the Utah Transit Authority, and the two agencies are actively working on the early acquisition of properties for a shared corridor.
How will it impact Great Salt Lake’s elevation?
The BRD system is expected to deliver 220,000 acre-feet annually. However, not all the water is expected to be depleted from the watershed. Much is expected to return to the watershed in the form of “return flows.” At full development, only an estimated 85,600 acre-feet would be fully depleted from the watershed. Current modeling indicates this level of depletion from the Great Salt Lake watershed would reduce the lake level by an average of about 8.5 inches and as much as 14 inches according to a White Paper published in 2016 by Utah State University, Water Resources, Salt Lake Community College, and the Utah Division of Wildlife Resources.
How much will it cost?
Cost estimates were produced for 13 scenarios of reservoir combinations. These estimates range between $1.5 and $2.8 Billion. An updated cost estimate will be prepared when the environmental studies are complete and alignment and design are determined.
Four water districts will deliver the water
As outlined in the Bear River Development Act, the BRD system, at full development, would deliver 220,000 acre-feet. Four water districts will deliver the water in the following amounts:
• Bear River Water Conservancy District – 60,000 acre-feet
• Cache Water District – 60,000 acre-feet
• Jordan Valley Water Conservancy District – 50,000 acre-feet
• Weber Basin Water Conservancy District – 50,000 acre-feet
