Designated Use: Irrigation and Stock
Recreational Use: Woodruff Narrows Reservoir is a popular fishing and boating location. In the winter it is a popular ice fishing location.
Associated Irrigation Diversions:There are presently 48,153 shares in the Woodruff Narrows Reservoir. Each share corresponds to one acre of irrigated ground. 39,967 shares (83%) are in Utah and 8,186 shares (17%) are in Wyoming.
Utah irrigators receive Woodruff Narrows water from the following ditches:
Francis Lee, Bear River Canal, Neville, Booth, Rees Land & Livestock, Crawford-Thompson, Randolph Woodruff, Big Creek Pumping Co. (pump out of Randolph Woodruff ditch), Dykens, Randolph Sage Creek, McMinn, Enberg, B.Q. West, Adam Pump).
Wyoming irrigators receive Woodruff Narrows water from the Pixley Canal, BQ West, Weston Pumps, and Johnson Pumps.
Associated Industrial Diversions:Water pumped out of Woodruff Narrows Reservoir and consumed by Chevron USA at their Whitney Canyon/Carter Creek Facility is purchased from Woodruff Narrows Reservoir Company. During the months when the reservoir is storing, the water pumped counts against the allowed reservoir storage in Woodruff Narrows.
Operational Discussion: Filling of Woodruff Narrows and Sulphur Creek Reservoir is handled on a proportional basis based on storage allocation (not strictly priority). Woodruff Narrow’s original Compact allocation is 76.4% of the combined and Sulphur Creek’s original Compact allocations is 23.6% of the combined.
The maximum amount of storage that can take place in one year is 18,400 acre- feet under the Original Compact and 20,960 acre-feet under the Amended Compact. Wyoming has allowed Woodruff Narrows, Broadbent, and Sulphur Creek Reservoirs to temporarily store a portion of their unconstructed original compact allocated storage when Bear Lake levels dropped below elevation 5911 in the early 1990’s. Releases of at least 10 cfs will be made per agreements between PacifiCorp and Utah Division of Wildlife Resources.
It should be noted that the Wyoming irrigators often have difficulty receiving their allotment of Woodruff Narrows storage. This problem is due to conveyance losses during dry periods when storage is needed, the inability to distinguish and regulate Wyoming storage vs. direct flow through the Lower Utah reach of the river, and the operational practices of the reservoir.
