NHD/WBD Technical Architecture Planning Meeting
May 11, 2010
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

Consistency Between States

Lake Pepin TMDL drainage area includes• 26 subbasins• Contributions from
Wisconsin, Iowa and South Dakota
MPCA Programs Depending on Data Linked to NHD
Assessment and listing process Water Quality permit issuance and
reissuance Phosphorus trading Storm water

Accommodating Multiple Business Needs
5
Regulatory boundary crosses road
• PWI represents State regulated boundary – the ordinary high water level
• Fisheries requires the open water basin
• NHD
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

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?
9
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)
