Key Structures and Diversions
QUINN BOURNE DIVERSION

PREPARED BY: Bear River Basin Planning Team

DATE: August 7, 2000









Diversion Description: The Quinn Bourne headgate consists of a wooden headwall with a 30-
inch culvert and a steel slide gate.



Quinn Bourne headgate structure





Diversion Location: The Quinn Bourne is the second highest diversion 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.

Estimated Diversion Efficiency: 



Calculated Diversion Efficiency = Conveyance Efficiency X Application Efficiency:





Conveyance Efficiency: 65%


Application Efficiency: 55%


Overall Diversion Efficiency: 36%








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:  Water is used entirely to irrigate meadow grasses, primarily 
Timothy, Meadow Foxtail, etc.3


Return Flows:  Return flow is primarily captured by Francis Larson ditch.


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

	
		Month
      (after initial Diversion)	 Percent of Return
		0			70%
		1			20%
		2			10%
                3                        0%
                                       100%
