  1. Minnesota perspectives: Current and future use NHD/WBD Technical Architecture Planning Meeting May 11, 2010 Mark Olsen Minnesota Pollution Control Agency Information Systems Office Susanne Maeder Minnesota Dept. of Administration Minnesota Geospatial Information Office

  2. Water quality is a priority for MN • Most surface water of the 48 contiguous states • Critical to $10 billion/year tourist industry, healthy agriculture and business economy • Water quality top priority for public • Impacts on economic growth • Number of impaired waters is growing

  3. Consistency Between States • Lake Pepin TMDL drainage area includes • 26 subbasins • Contributions from Wisconsin, Iowa and South Dakota

  4. MPCA Programs Depending on Data Linked to NHD • Assessment and listing process • Water Quality permit issuance and reissuance • Phosphorus trading • Storm water • MS4 • Construction • Industrial

  5. Accommodating Multiple Business Needs Regulatoryboundary crosses road • PWIrepresents State regulated boundary – the ordinary high water level • Fisheriesrequires the open water basin • NHD

  6. Future Needs • More and better tools • Generalization, conflation, editing and markup • Enhanced usability • More and better data • Stormwater • Lidar • High Resolution NHDPlus • Enhanced analysis capabilities • Network traversal • Model integration

  7. The Minnesota NHD Maintenance Process USGS - NHD MnRAD Steward MnRAD User Distribution Database Pgdb, shapefiles, direct use Mn Distribution Database NHDGeoEdit, Conflation, Indexing Tools, ArcGIS via IMS, ArcIMS, ArcHydro NHDGeoEdit, Indexing Tools, ArcGIS via IMS, ArcIMS Production Database Mn Production Database Local Edits National Updates

  8. Desktop Requirements • NHDGeoEdit, NHDGeoConflate • Simplify Tools and Entire Update Process to extent practicable • Timing from desktop update to NHD Distribution • Software versions – Timing • Web Reporting • HEM Desktop Tool • Need robust HEM Tool for creating local events • Heavy user of synchronization process

  9. MN DNR-NHD Synchronization Process • Multiple Data Sets, Multiple Business Needs • Lakes & Streams Data: NHD, DNR Hydro GDB • Watersheds: WBD, DNR Catchments (huc-16) • Wetlands: NWI Update in progress • Current Project: Develop Process for data harmonization • One more conflation – bring together best of both • Shared Editing Environment in the future? • Accommodating other data • Technology Issues • Update process not dependent on extract to desktop? • Capabilities of replication?

  10. Goals and Timing • Short-term (1-2 years) • Resolve DNR-NHD Issues: Complete Conflation,Pilot Shared Editing • Additional data: storm water, ditch inventories (drain tiles?) • Begin NHDPlus for high-res • More robust local event handling (Mn) • More robust hydro navigation tools, incl web-based • Medium-term (3-5 years) • Shared editing of state updates; redefined stewardship authorities • State single hydro database (NHD as keystone) • Web-enabled tools • Long-term (6-10 years)
