Integration Update on Spatial Water Datasets and GIO Related Issues for Enhanced Hydrography

This document provides an update on the integration of key spatial water datasets, including the National Elevation Dataset (NED), National Hydrography Dataset (NHD), and Watershed Boundary Dataset (WBD). It outlines the collaboration among various federal agencies such as NOAA, USGS, and USEPA in developing high-resolution datasets essential for water resource management. Highlights include the completion of 2101 HUCs processed, coordination efforts, and the review process for enhanced standards and tools in spatial water data aimed at improving the effectiveness of watershed management initiatives.
