Analyzing Irrigation Practices: Bear River Canal Company
December 3, 2015
By
Carl W. Mackley, P.E.
Utah Division of Water Rights
and
M.E. Student, Utah State University
Bear River Basin Located in Utah, Idaho, and Wyoming
Project Area• Close-up of Bear River Canal
Company Service Area• Location in B.R. Basin
Determine What Factors Affect Water Use(What Data To Gather)
• Precipitation Temperature
• Land Use • Water Availability
Gathering Data: Precipitation and Temperature
(PRISM Climate Group)
Gathering Data: Land UseFrom Utah Div. of Water Resources & AGRC
Gathering Data: Water AvailabilityFrom USGS and Pacificorp
• Natural Flow at USGS Corinne Gage• Bear Lake Storage Allocation Data Courtesy Of:
Discharge of the Bear River near Corinne, Utah

Results: Scoring Each Year(Lower Score = Higher Ranking)
Conclusions:
1. Temperature plays a fairly insignificant role.
2. In-season precipitation reduces diversions.
3. The quantity of natural flow available affects storage use.
4. Because of a senior priority, BRCC regularly receives its water.
5. Land use acreage and crop type really affects the amount of water diverted.
Are there any questions?
Such as…..
1. Data Use or Sources
2. How GIS Was Used
3. Conclusions
4. Others…
