The StreamCat Dataset: Accumulated Attributes for NHDPlusV2 (Version 2.1) Catchments for the Conterminous United States: National Coal Resource Dataset System

Published by U.S. Environmental Protection Agency, Office of Research and Development (ORD), Center for Public Health and Environmental Assessment (CPHEA), Pacific Ecological Systems Division (PESD), | U.S. Environmental Protection Agency | Metadata Last Checked: July 13, 2025 | Last Modified: 2023-11-13
This dataset represents the coal mine density and storage volumes within individual, local NHDPlusV2 catchments and upstream, contributing watersheds based on the National Coal Resource Dataset System (NCRDS). Attributes of the landscape layer were calculated for every local NHDPlusV2 catchment and accumulated to provide watershed-level metrics. The National Coal Resources Data System (NCRDS) began as a cooperative venture between the USGS and State geological agencies in 1975 and focused on the stratigraphy and chemistry of coal. Web pages have been developed to query data within both the USCOAL database and a subset of the USCHEM database. The USTRAT database, due to its size and complexity, was first made available in 2011 for direct query through web pages. The (coal mine sites/AreaSqKm) were summarized and accumulated into watersheds to produce local catchment-level and watershed-level metrics as a point data type.
