2010 NHD status report by Evan Fedorko

1. The WV NHD Stewardship Program Evan J Fedorko

2. Outline What is NHD? NHD Applications NHD Data Source NHD Stewardship Overview NHD Stewardship in WV How you can participate in Stewardship Where to get NHD Data and tools

3. NHD The National Hydrographic Dataset is a comprehensive set of digital spatial data representing the surface water of the United States using common features such as lakes, ponds, streams, rivers, canals, and oceans. Also includes the Watershed Boundary Dataset, aka WBD.

4. NHD Applications Base layer for hydro features in cartographic applications. Model features include: Flow direction network that traces the water downstream or upstream. An addressing system to link specific information about the water to a point such as water discharge, water quality, and fish population.

5. NHD Applications (2) Model features allow for advanced analysis such as: Publishing and Analyzing water pollution data Prioritizing watersheds for conservation Incident command for Toxic spills into water- ways

6. NHD Data Scale of NHD data varies by state West Virginia, and much of the US, is 1:24,000 scale data Includes all water features from USGS Topographic maps This means much of WV’s data is quite old.

7. Stewardship The term “stewardship” refers to the mechanism by which the NHD data is improved and maintained. Large Federal agencies do not have the knowledge to maintain these datasets, so… Local Stewards are encouraged to take over and maintain this data, with support from the USSGS

8. Stewardship in WV Memorandum of Understanding Between WV Office of GIS Coordinator, NRCS and the USGS Identifies two stewards: WVOGC (NHD), NRCS (WBD) Identifies a technical lead: WVGISTC Signed, sealed and delivered! Year one proposal Submitted and approved!

9. Stewardship in WV (2) USGS NHD Stewardship Program NHD National WV Office of GIS Coordination NHD Steward Stewardship Technical Lead WV GIS Technical Center Primary Sub-Stewards NHD Error Reporting Tool e.g., WVDEP, USFS, WVDNR Stakeholders and Stewardship Mechanisms NHD Users Group NHD Training and Policies NHD Data Users

10. Stewardship in WV (3) Year One Proposal Players: WVGISTC, NRAC, WVDEP Task 1: Stewardship program establishment and organization Task 2: Editing of known errors Task 3: High change area targeted editing (research)

11. Stewardship in WV (4) How can you participate? By noting and reporting errors in NHD By submitting your water feature data to the NHD stewards By attending free training on using the NHD

12. NHD Data Data: Nhd.usgs.gov www.wvgis.wvu.edu (WVGISTC), search keyword “NHD” Available from USGS and WVGISTC in ESRI Geodatabase format, and from WVGISTC additionally as shapefiles Available nationwide from USGS and for WV from WVGISTC
