Description
Small-scale GIS data layers compiled by the National Park Service for a Baseline Water Quality Data Inventory and Analysis Report. The layers were used to map locations of water quality monitoring stations, industrial discharges, drinking intakes, water gages, and water impoundments. Data layers include roads, hydrography, political boundaries, USGS quadrangle outlines, hydrologic units, and trails, generally at a scale of 1:100,000.
Use Cases
Map water quality monitoring station locations based on the hydrography and station data layers.
Analyze potential pollution sources based on the industrial facilities discharges layer.
Assess drinking water supply infrastructure based on the drinking water supplies layer.
Model hydrological features and watersheds based on the hydrologic units and river reach data.
Strengths
Data compiled by the National Park Service Servicewide Inventory and Monitoring Program and Water Resources Division.
Layers are generally at a consistent 1:100,000 scale.
Data sources include six U.S. Environmental Protection Agency national databases.
Limitations
