Drainage Basins and Water Management Districts

Overview This map service presents polygon data for drainage basin boundaries and water management district cumulative impact basins. It supports mapping, querying, and data access for watershed and basin boundary information. Layers Drainage Basins 1997 and Drainage Basins 1995 show basin area boundaries with supporting basin identifiers and size attributes. Hydrologic Unit Code Basins displays major basin units determined by the Department of Environmental Protection. Water Management District Cumulative Impact Basins shows district basin areas compiled from the five water management district GIS sources. Characteristics The service visualizes polygon features for hydrologic basin boundaries, basin names, basin codes, area measurements, and related reference attributes. The 1997 drainage basins are symbolized by unique values using the basin code field, the hydrologic unit code basins are symbolized by unique values using basin names, and the water management district basins are symbolized by unique values using district names. Popups expose basin identifiers, names, area values, perimeter measurements, and related basin attributes. Temporal summary: The content includes historical basin versions from 1995 and 1997, along with a compiled 2015 water management district basin layer. The layers represent mapped basin boundary snapshots that support comparison of basin geography across these source dates. Geographic Coverage The service covers a broad regional extent in the coordinate reference system identified as 102967, with basin polygons spanning the full service area shown in the provided extent. Use Cases This service is useful for watershed reference, basin boundary review, water management planning, environmental reporting, and map-based inspection of basin attributes and district coverage.
