Comprehensive GIS Data Sources for Water Resources Management

This resource provides an extensive compilation of GIS data sources essential for water resource management, featuring contributions from experts like David R. Maidment and David G. Tarboton. It encompasses various datasets including hydrologic unit codes, watershed boundaries, and river networks from organizations such as the USGS and USDA. Users can access real-time and historic water data, mapping tools, and federal guidelines for watershed management. This resource is invaluable for researchers, policymakers, and professionals in the field of water resources.
