Key Structures and Diversions
S.P. (RAMSEY) DIVERSION
(Also called Adin Brown)

PREPARED BY: Bear River Basin Planning Team

DATE: August 7, 2000




Diversion Description: The headgate structure consists of a deteriorated concrete headwall, a 48-inch CMP culvert, and a slide gate. The actual river diversion is located approximately 2000 feet upstream of the gate. A dozer is typically used each year to dam the river.
S.P. (Ramsey) Headgate
Diversion Location: Diversion is on the Upper Bear in Wyoming as shown on the location map hereafter.

Latitude       N 41° 18' 04.2"

Sulphur Creek Dennis Moon 4 100%
Sulphur Creek Charles Nixon 137 34%
Sulphur Creek Gilda Sims 219 50%
Sulphur Creek Michael Sims 40 50%

Irrigation Practices: Flood Irrigated except for about 80 acres sprinkled. Sprinkled acreage is alfalfa.3

Estimated Diversion Efficiency:

Calculated Diversion Efficiency = Conveyance Efficiency X Application Efficiency:
Conveyance Efficiency: 60%
Application Efficiency: 55%
Overall Diversion Efficiency: 33%

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: Mostly meadow grasses. Approximately 80 acres is alfalfa.3

Return Flows: Return flow is primarily split between the Chapman Canal (approx. 50%) and the Bear River (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%
