      The effects of contour furrows and gully plugs on erosion and sedimentation within the Cisco Basin, Utah, were evaluated over a 3- to 4-year period. Soils on the study area were generally less than 10 cm deep and were developed from Mancos shale and sandstone. Contour furrows and gully plugs together held all runoff and sediment, while contour furrows alone held only a portion of the runoff and sediment. Difficulties 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.
