Key Structures and Diversions
Crown & Pine Grove Diversions

PREPARED BY: Bear River Basin Planning Team

DATE: August 7, 2000











Diversion Description:  The "Crown Ditch" and "Pine Grove Canal" are separate conveyances 
with separate headgates.  The two canals merge approximately 50 yards downstream of 
the Crown diversion.  There is a divider box located approximately 1/2 mile further 
downstream. As a matter of practicality, these two diversions are typically regulated 
together.


The Crown gate structure consists of a 60-inch diameter squash pipe with a slide gate.  
The Pine Grove gate structure is virtually identical to the Crown.



Crown Headgate




Diversion Location:	Diversions are on the Upper Bear in Wyoming.  Irrigated lands are located 
in Wyoming as shown in the respective location maps hereafter.



Crown:

Latitude 	N   41° 00' 53.2"

Longitude    	W  110° 52' 23.9"



Pine Grove:

Latitude 	N   41° 00' 57.7"

Longitude    	W  110° 53' 07.0"







Conveyance Description: Both the Crown and the Pine Grove are open channel canals.


	
	
Crown Ditch -  	Approximately 26,400 feet in length.1
	
Pine Grove Canal -  	Approximately 36,960 feet in length.1

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


Return Flows:  Return flow is split between the Lewis Ditch (approx. 25%), Mill Creek 
(approx. 25%), and the Meyers No. 2 Ditch (approx. 50%).


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%

Notes:

*1. No published records are available for this diversion 1970

2. Crown and Pine are two separate diversions with channels merging about
50 yards downstream of Crown. They split about 1/2 mile further downstream.
The two canals are typically regulated jointly near the head.
