COVEY CANAL DIVERSION

PREPARED BY: Bear River Basin Planning Team

DATE: August 7, 2000

Diversion Description:The Covey Canal headgate consists of two 62-inch rectangular steel gates set into a concrete headwall. The structure was built in the early 1990’s. There is a concrete cut-off wall across the river to divert flows. There is a side outlet gate to pass low flows downstream.

Diversion Location: The Covey Canal headgate structure is located on Smiths Fork, tributary to the Bear River. Brunner Creek and Spring Creek are also captured by the Covey Canal. Diversion records are maintained (and regulation occurs) at both confluences as well as at the headgate. The Diversion is regulated as part of the Central Division of the Bear River Compact. See location map hereafter.

Associated Storage Rights: None

Irrigation Practices: Irrigation practices are mixed (Approx. 70% flood irrigation, 30% center pivot sprinkler irrigation).³

Estimated Diversion Efficiency:

Calculated Diversion Efficiency = Conveyance Efficiency X Application Efficiency:

Conveyance Efficiency: 45%

Application Efficiency: 65%

Overall Diversion Efficiency: 30%

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 acreage is mixed between meadow grasses, alfalfa, and grains (primarily oats). In general, the sprinkled acreage is alfalfa and grains.³

Return Flows: Return flow is primarily captured the Whites Water Ditch (approx. 10%) with the remaining 90% returning 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%

Other Operational Information: The Covey Canal is operated by the Smiths Fork Irrigation District. The canal is very long with the most senior water rights appropriated to irrigated lands near the end of the canal.

SUBJECT:	Appendix D Key Structures and Diversions COVEY CANAL DIVERSION

PREPARED BY:	Bear River Basin Planning Team

DATE:	August 7, 2000

Diversion Description:The Covey Canal headgate consists of two 62-inch rectangular steel gates set into a concrete headwall. The structure was built in the early 1990’s. There is a concrete cut-off wall across the river to divert flows. There is a side outlet gate to pass low flows downstream.	*Covey Canal headgate structure*
Covey Canal cut-off wall across the Smiths Fork	Diversion Location: The Covey Canal headgate structure is located on Smiths Fork, tributary to the Bear River. Brunner Creek and Spring Creek are also captured by the Covey Canal. Diversion records are maintained (and regulation occurs) at both confluences as well as at the headgate. The Diversion is regulated as part of the Central Division of the Bear River Compact. See location map hereafter. Latitude N 42° 07' 19.6" Longitude W 110° 54' 08.3"
Covey Canal cut-off wall across the Smiths Fork	Conveyance Description: Open channel canal, approximately 121,000 feet in length¹

Conveyance Efficiency:	45%
