Sediment erosion and deposition in two sets of paired (treated and untreated) upland drainages in the Torreon Wash watershed, upper Rio Puerco Basin, New Mexico, were examined over a 3 1/2-year period from spring 2009 through fall 2012. The objective was to evaluate the effectiveness of shallow, loose-stone check dams, or “one-rock dams,” as a hillslope gully erosion stabilization and mitigation method, and its potential for retaining upland eroded soils and decreasing delivery of sediment to lower ephemeral stream channels. Two high-resolution topographic surveys, completed at the beginning and end of the study period, were used to assess the impact of the mitigation measures in both Penistaja Tributary Arroyo...

Mean annual streamflow was determined for each year of the streamgage record using the U. S. Environmental Protection Agency (EPA) DFLOW computer program (Rossman, 1990). A shapefile specifying streamgage locations was loaded into the program and divided into four quadrants to facilitate more efficient program operation. For each quadrant, appropriate streamgages were selected by the program based on period of record and regulation status. Daily discharge information for each streamgage was downloaded from the National Water Information System (NWIS). The downloaded data were used in the computation of mean annual streamflow at each location and was output as site-specific, tab-delimited files. The process was...
