Montana is modernizing their stream and waterbody mapping data, which relies on the current National Hydrography Dataset (NHD). NHD is outdated and lacks detail for local features like canals and small drainages. With statewide lidar acquisition nearing completion, the next evolution of water course mapping will adopt the USGS 3D Hydrography Program (3DHP). 3DHP provides a new data model, more accurate and consistent data, and connections to water reporting systems. 3DHP will enable hydrographic analysis and visualization for a broad range of applications. Get involved to help improve Montana’s water data.
