Chaco Culture National Historical Park Water Quality GIS Layers

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, gages, and impoundments based on EPA databases. Data includes features like roads, hydrography, and political boundaries, generally at a 1:100,000 scale.

Use Cases

• Map water quality monitoring station locations based on EPA STORET database data mentioned in the description
• Analyze potential pollution sources based on industrial facility discharge locations referenced in the report
• Visualize hydrological features and infrastructure like water gages and impoundments for park management
• Create base maps for environmental assessments using compiled layers like roads, trails, and political boundaries

Strengths

• Data compiled from six authoritative EPA national databases for water quality analysis
• GIS layers include multiple contextual features such as roads, hydrography, and political boundaries
• Spatial scale is generally specified as 1:100,000

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The data layers included vary depending on availability, indicating potential completeness gaps
