Description: <p><strong>Overview</strong></p><p>This feature service provides a polyline representation of river and stream features compiled from National Hydrography Dataset information for the CW area. It supports mapping and analysis of linear water features and includes identifiers and network attributes that help describe each river segment within the hydrographic network.</p><p><strong>Content</strong></p><ul><li><strong>Geometry:</strong> Polyline features representing rivers, streams, and related flow paths.</li><li><strong>Attribute information:</strong> Feature identifiers, names, reach codes, flow direction, length, network status, and source-related metadata.</li><li><strong>Use cases:</strong> Hydrologic mapping, watershed planning, network tracing, environmental analysis, and reference mapping for surface water features.</li></ul><p><strong>Purpose</strong></p><p>The service supports GIS workflows that require detailed river network data for viewing, querying, and integrating hydrographic information into spatial analysis and cartographic products.</p>
