Streamflow from two drainages of the Davis County Experimental Watershed, Utah, was evaluated with respect to changes in distribution and volume following trenching of one of the drainages in 1964. Fifteen percent of the Halfway Creek drainage was trenched according to established U.S. Forest Service methods. Twelve years of records before trenching and four years of records after trenching were analyzed.
Analysis of the annual streamflow, the low streamflow period, and the spring streamflow period indicated no significant change in either volume or distribution of streamflow as a result of trenching. This conclusion was further substantiated by supplemental data of precipitation, soil moisture, snowpack water equivalent, and vegetation.
