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:	40%
Application Efficiency:	55%
Overall Diversion Efficiency:	22%

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 Meadow Foxtail, etc.³

Return Flows: Return flow is split between the Sulphur Creek Reservoir (approx. 60%) and Sulphur Creek below the reservoir (approx. 40%).

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%

Other Operational Information: The Bear Canal operates year-round for stock watering in the Hilliard area during the winter months.³
