Charles F. Roberson Ditch, Ham's Fork River

Diversion Description: Diversion consists of a single 24" diameter Waterman slide gate. A small rock diversion dam exists.1

Diversion Location:
Source: Ham's Fork River, Trib. Black's Fork River, Trib. Green River
Section, Township, Range: 24, 21, 114M

Conveyance Description: Open Channel Canal, approximately 4« miles in length.1

Storage Rights: None.

Estimated Canal Losses: Slightly greater than typical (10-15%).1

Irrigation Practices: Lands are entirely flood irrigated.1

Crop Types / Consumptive Use: Water is used to irrigate almost entirely native grass hay and pasture.1

Return Flows: Ham's Fork River above Opal, Wyoming.

Other Operational Information: Conveyance losses through the Ham's Fork River channel itself are significantly high. Ditch is typically turned on in early May. As water levels in Ham's Fork decrease, water users typically practice self-regulation by rotation or reducing water taken from the river. Ditch is typically turned off in July.1
