The U.S. Geological Survey’s (USGS) SPAtially Referenced Regression On Watershed attributes (SPARROW) model was used to aid in the interpretation of monitoring data and simulate nutrient loads in streams across the Midwest Region of the United States. SPARROW is a hybrid empirical/process-based mass balance model that can be used to estimate the major sources and environmental factors that affect the long-term supply, transport, and fate of contaminants in streams. The spatially explicit model structure is defined by a river reach network coupled with contributing catchments. The model is calibrated by statistically relating watershed sources and transport-related properties to monitoring-based water-quality load...
The Kanab Creek Project Area encompasses 130,000 acres in southern Utah. This project area receives National attention because it is home to the Paunsagunt mule deer herd which are prized by trophy hunters, and because it supports the southernmost population of greater sage grouse within the western United States. One of the focuses of this project area has been to conduct treatments that cross jurisdictional boundaries, by working closely with private landowners, Natural Resource Conservation Service (NRCS) and Utah’s Watershed Restoration Initiative, to provide landscape-level benefits for sage grouse. Telemetry data show that sage grouse are actively using older treatment areas, and newer treatments will expand...

Background information.—The Powell River watershed has a long history of coal mining. Prior to August 3, 1977, Virginia laws and regulations required the reclamation of areas affected by coal surface mining, but there were no regulations addressing reclamation of underground mines. Flows or seeps from these abandoned mines have long degraded the waters of the Powell River watershed (U.S. Department of Agriculture, 2008). Water that is discharged from these sites can be highly acidic and it commonly contains high concentrations of dissolved iron and aluminum sulfates. This acid mine drainage degrades the water quality of streams and water supplies and is a major contributor to aquatic habitat degradation. Led by...
