Effects of Gully Plugs and Contour Furrows on Erosion and Sedimentation in Cisco Basin, Utah
Journal of range management
Site Description B. COLTHARP The areas selected for study are located approximately 5 miles to the west and south of the town of Cisco, Grand County, Utah. This area, Highlight: The effects of contour furrows and gully plugs on known as Cisco Basin, is bounded on the north by the Book Cliffs and erosion and sedimentation within the Cisco Basin, Utah, were on the south by the Colorado River. It is typical of the upper Colorado evaluated over a 3-to byear period. Soils on the study area were
... Drainage basin of western Colorado and much of Carbon, generally less than 10 cm deep and were developed from Mancos Emery, Garfield, Grand, Kane, San Juan, Uintah, and Wayne shale and sandstone. Contour furrows and gully plugs together aunties in eastem Utah. Mean elevation above sea level is 1,280 to held all runoff and sediment, while contour furrows alone held only a portion of the runoff and sediment. Diffkulties in constructing furrows on the contour resulted in a shortened useful life of the structures. Projected life expectancy of the contour furrows ranged from 6 to 12 years; for the gully plugs the projected life expectancy was from 14 to 33 years.
