Key Structures and Diversions
MYERS No. 2 DIVERSION

PREPARED BY: Bear River Basin Planning Team

DATE: August 7, 2000










Diversion Description:The diversion headgate structure consists of a very old, deteriorated 
wooden head wall with a 36-inch slide gate.



Myers No. 2 Headgate





Diversion Location: Diversion is on the Upper Bear in Wyoming.  Irrigated lands are located in 
Wyoming as shown in the location map hereafter.

					

Latitude  	N   41° 04' 10.0"	

Longitude     	W 110° 55'  45.3"





Conveyance Description: Open Channel Canal.

Irrigation Practices:  Land is all flood irrigated.3 


Estimated Diversion Efficiency: Canal losses are relatively high due to porous nature of soils in 
the higher reaches of the Upper Bear.  





Calculated Diversion Efficiency = Conveyance Efficiency X Application Efficiency:



Conveyance Efficiency: 50%


Application Efficiency: 55%


Overall Diversion Efficiency: 27%








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 mixed meadow grasses, 
primarily Timothy, Meadow Foxtail, etc.3


Return Flows:   Return flow is primarily intercepted by Myers Ditch No. 1.


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%
