Bear River Basin Water Plan
Technical Memoranda

SUBJECT:	Appendix D Key Structures and Diversions WHITES WATER DIVERSION
PREPARED BY:	Bear River Basin Planning Team
DATE:	August 7, 2000

Diversion Description: The Whites Water headgate consists of a concrete headwall with a single 9-foot wide rectangular wooden gate.	Whites Water headgate structure
Diversion Location: The Whites Water diversion is located on the Smiths Fork, tributary to the Bear River. The diversion is regulated as part of the Central Division of the Bear River Compact. See location map hereafter. Latitude   N 42° 05' 52.2" Longitude   W 110° 56' 14.5"

Conveyance Description: Open channel canal, approximately 29,040 feet in length.¹

Irrigation Practices: Lands west of Highway 89 are flood irrigated (approx. 60%). Lands on the east side of Highway 89 are sprinkler irrigated using hand lines and side wheel rolls (approx. 40%).³

Estimated Diversion Efficiency:

Calculated Diversion Efficiency = Conveyance Efficiency X Application Efficiency:

Conveyance Efficiency:	60%
Application Efficiency:	65%
Overall Diversion Efficiency:	40%

Conveyance efficiency is estimated by total length of main canal. Application efficiency for flood irrigation and sprinkler irrigation is estimated at 55% and 85% respectively.

Crop Types / Consumptive Use: Irrigated lands are mostly alfalfa (approx. 70%) with some grains. The remainder of the acreage is meadow grasses.³

Return Flows: Return flow reportedly surfaces at Garrett springs, tributary to the Bear River.

The following return flow pattern was adopted for modeling in this study are as follows:

	
		Month
      (after initial Diversion)	 Percent of Return
		0			50%
		1			25%
		2			15%
                3                       10%
                                       100%
