Storage Rights: None.

Estimated Canal Losses: Greater than typical losses (25%) are experienced in the first mile of the ditch, typical losses (10%) are experienced in the lower reach.¹

Irrigation Practices: Lands are flood irrigated.¹

Crop Types / Consumptive Use: Lands are native grass hay and pasture.¹

Return Flows: Return flows are delivered to Green River at Tarter Gulch.²

Other Operational Information: The canal is typically turned on the first of May and off in mid-July.¹
