Summary
This spatial data set was created by the U.S. Geological Survey (USGS) to represent populations that did not have access to municipal sewer service in the Pacific Northwest region of the United States (Hydro Region 17; Major River Basin 7 (MRB7)) in 2002.
This data set was intended to represent spatially explicit nutrient loadings in the application of the SPARROW (SPAtially Referenced Regressions On Watershed attributes) model to assess total nitrogen and total phosphorus conditions in surface water in Major River Basin 7 (MRB7) using the National Hydrography Dataset as a hydrologic framework.
