Snow Fencing to Increase Streamflow on Rangelands

Abstract:

Snow deposition and water yield were increased 55% and 127% respectively, and duration of surface runoff was lengthened 17 days in response to snow fencing a sagebrush-covered watershed in southern Wyoming. The Wyoming snow fence was 3.8 m tall and 800 m long. Treatment evaluations were based on 10 years of pretreatment and 6 years of posttreatment streamflow information. The value of additional water would have to be $0.077/m3 ($95.00/acre-ft) to amortize fence construction costs based on a 25-year project life.
