  1. Managing the Nation’s Hydro Events NHD Stewardship Conference 2012

  2. Hydrography Event Management (HEM) ToolsUpdate Ariel Doumbouya

  3. NHD Update Tools and NHD Events • HEM Job Type • All HEM required feature classes and tables are delivered • Requires a subset of the normal QC

  4. What’s Next? • ArcGIS 10.1 • Web

  5. More Information: http://nhd.usgs.gov

  6. Using event data in analysis and reporting: How Oregon BLM Uses Event Overlay Jay Stevens Bureau of Land Management Oregon State Office

  7. PFC (Proper Functioning Condition) protocol- used for determining appropriate timing and design of riparian-wetland restoration projects. The ratings can be aggregated and analyzed at the watershed scale.

  8. Historical Events • First version of Aquatic Resource Information Management System (ARIMS) database deploys in 2000. Used ArcView and Informix. Uses Linear Events on routed line-work(LLID system) • Decision is made in 2006 to switch to NHD data model for PNW Framework Hydrography. Forest Service and BLM are main drivers. • Development of Hydro Event Management (HEM) tools begins in 2007 with Forest Service event-maker app as starting point. • ARIMS redesigned to use HEM and NHD in ARCGIS 9 environment in 2008 • Legacy event data (millions of records) are migrated to NHD and HEM format in 2008-2009 • Subsequent HEM development with EPA and USGS support add enhancements to system.

  9. Current System Overview • HEM and ARIMS work together in ARCGIS environment to manage aquatic data stored as events on the NHD route system. • All event data and NHD data used for linear referencing stored in same SDE Oracle instance • Deployed on Citrix server farm • Users located in central, district, and field offices.

  10. What kind of aquatic data are we collecting? • Fish Distribution • Riparian Wetland Condition • Stream Surveys /Geomorphology • Flow characteristics • Water Quality Data

  11. Fish presence/absence data used to prioritize stream restoration work, fish barrier removal, and to establish riparian buffers.

  12. Western Oregon Plan Revision Map Showing Land Use Allocations

  13. Riparian Buffers are an Important Component

  14. Criteria from multiple event tables needed to calculate riparian buffer distance BLM Fishbearing Status BLM Flow for Planning

  15. Selection for varying buffer distances can be made easily when both events’ attributes are on same set of flowlines ("PLANFLOW" = 'I' or "PLANFLOW" = 'P' ) and "FISHBEARING" = 'ANV'

  16. Publication/Analytical DatasetsRequirements • Need to be able to select and report miles of stream by fish presence, riparian condition, periodicity, etc. • Can’t have duplicate copies of geometry (no double-reporting miles) • Some of the data is temporal so need to extract most recent information

  17. Analytical/Publication DatasetsMain Techniques • ARCGIS Event Overlay – Not line on line geometry overlay. Event overlay uses tabular route and measure info to INTERSECT or UNION event tables thus adding new fields from each successive overlay. • Oracle PL/SQL Analytical Queries – Used to analyze temporal event data to bring most recent records forward into publication dataset. Riparian Functioning data (PFC) and Fish presence data are processed this way.

  23. Montana Hydrography Stewardship Model • Hydrography is one of 14 Montana Spatial Data Infrastructure (MSDI) Framework Layers. • Montana adopted the NHD as the state Hydrography Framework. • The Montana State Library (MSL)/Natural Resource Information System (NRIS) has an agreement with the USGS to act as the state level data steward for the NHD and… • NRIS is recognized by the Montana Land Information Advisory Council as the state steward of the MSDI Hydrography Framework.

  24. Montana Hydrography Stewardship Activities • NRIS provides staff for NHD Stewardship and the NHD Technical Point of Contact • NRIS is a data provider and not an end user so our focus is on getting state hydrography users together to build the dataset that they need • NRIS holds regular Hydrography Workgroup meetings and develops a Hydrography Strategic/Business Plan • Current stewardship focus on getting core state agencies to use a common Hydrography. • Projects underway at the Department of Natural Resources and Conservation, Department of Fish, Wildlife and Parks, and the Department of Environmental Quality. • All of these projects take an event management approach to leveraging the value of the NHD for filling state agency business needs.

  25. Montana Hydrography Stewardship Projects Montana Department of Natural Resources – Water Rights Point of Diversions – Troy Blandford will give a brief overview of the project and discuss the success they have had trying different approaches for matching up dams in the Water Rights database to the NHD. Montana Department of Environmental Quality – Water Quality Data – Michael Pipp will talk about the data management workflows that were developed to allow the agency to use the continuously changing NHD as a reference dataset. Montana Department of Fish Wildlife and Parks – fisheries data and the requirement of Whole Stream Identifiers. Much of the fisheries work done by this agency is in collaboration with other pacific nw states. The fundamental organizing unit for their data management is the full river. We are exploring the possibility of developing a type of compund event that may meet their business needs.

  26. Dams to NHD: An Exercise in Locating Dams from the Montana Water Rights Database. Troy Blandford Montana DNRC NHD Stewardship Conference March 29-30, 2012 New Orleans, LA

  27. Overview of the Bigger Project • POD2NHD Overall Goal: • Assess the feasibility of geospatially enabling the DNRC Water Rights Database and integrating it with the NHD.

  28. A large majority of the diversions: DAMS Total ~ 180,000 * Active water rights only, March 2012. Minimum counts (dissolved by unique legal land description).

  29. The majority of the diversions: DAMS Example of Livestock Direct from Source Total ~ 180,000 * Active water rights only, March 2012. Minimum counts (dissolved by unique legal land description).

  30. Potential Enhancement to Current Dam Datasets

  31. Potential Enhancement to Current Dam Datasets

  32. The Driving Forces • National Inventory of Dams (NID) • Dams on State Lands • USGS StreamStats Amount of time to place all dams estimated at over a year.

  33. Making the Project Manageable • Automate the process as much as possible. • Use multiple sources and their spatial relationships.

  34. Examples of Challenges

  35. Results Successfully automated the placement of over 23K (55%) of the water right dams to NHD.

  36. What’s next • Only 20K dams and 140K more surface water right points of diversion to go. • Attribute the dams • Continue to investigate referencing additional means of diversion types (significant effort; not as easy to place as dams; may not have as much success automating).
