  32. Challenges! • Establish an equitable funding solution for delivering computationally intensive shared services. (Eliminate WCF disincentive for providing web services) • Deploy an Enterprise Identity Management Solution in FY 05 • Establish a functional shared development environment for the Agency

  36. Generalization Attribute

  37. Elevation-based NHD Catchments • Based upon the integration of the: • NHD • National Elevation Dataset (NED) • Watershed Boundary Dataset (WBD) • Catchment attributes: • Precipitation • Temperature • Elevations • Slope • Land Cover • etc

  38. Flow Volume and Velocity • The Goals: • Catchments for every NHD reach to tie overland flow to the network • Enhance NHD with elevation-derived attributes such as slope • Improved velocity estimates based upon new Time of Travel database • Estimate stream flow volume (mean annual) and velocity Enable NHD-based SPARROW, Time-of-Travel models • The Team: • EPA • USGS Mapping and Water Disciplines • U of Texas

  39. Assessing Recovery Potential of Impaired Waters • Joint OW/ORD project • Recovery potential: the likelihood of an impaired water to reattain Water Quality Standards, given its ecological capacity to regain lost functions, its exposure to stressors, and its social context. • Opportunity to consider landscape factors related to recovery potential within drainage areas and stream corridors, using GIS

  40. Assessing Recovery Potential of Impaired Waters (cont’d) Some Implications of this Project: • Over 800 impaired (303d-listed) streams in Illinois, yet their exact watersheds are not delineated; this stumbling block prevents rapid, statewide GIS assessment in routine water program planning. • There are tens of thousands of similar waters nationally. • Availability of good drainage area delineations/tools removes an obstacle to statewide comparative spatial assessments such as recovery potential screening.

  41. Partners US Forest Service Technical Support Working Group (TSWG) DTRA EPA USGS Water sources are vulnerable Preparedness will reduce consequences to the public of an attack Incident Commanders need timely information to act effectively Tool will provide ICs critical information when they need it Water Modeling for the Incident Commander (ICWater)

  43. OW is Covered with WATERS • Immediate Office • Management & Operations Staff • Communications Team • Water Policy Staff • Resource Management Staff • American Indian Environmental Office • Office of Wetlands Oceans & Watersheds • Assessment & Watershed Protection Division • Oceans & Coastal Protection Division • Wetlands Division • Office of Wastewater Management • Municipal Support Division • Water Permits Division • Office of Ground Water & Drinking Water • Water Security Division • Drinking Water Protection Division • Standards & Risk Management Division • Office of Science & Technology • Engineering & Analysis Division • Health & Ecological Criteria Division • Standards & Health Protection Division

  44. Endangered Species: An Example Potential Use of NHD in Pesticide Risk Assessments • The Office of Pesticide Programs is exploring the use of the NHD and value-added attributes in a variety of applications related to pesticide risk assessments. • In this example, NHD navigation tools are combined with the NLCD and NHD catchments (Thiessen-based) to estimate the direct and indirect effects of agricultural pesticide use on endangered aquatic species. • Figure 1 shows Percent Cropped Area (PCA) calculated for each NHD catchment. • Figure 2 shows NHD stream segments rated based on measurements of agricultural intensity. Red represents direct affects, and yellow, the indirect effects of agricultural pesticide use. Figure 2 Figure 1

  45. USGS Water District NHD Rollout • 25,000 gages linked to NHD • Gage drainage areas with attributes • NHD with linked water program data • NHD Plus (as it becomes available) • Recognized federal and state partner in the field

  46. USGS NAWQA SPARROW Modeling • Original USGS SPARROW (Spatially Referenced Regressions on Watershed Attributes) water quality models based upon Reach File Version 1 (RF1) 1:500,00-scale • Success of EPA-funded NHD-based New England SPARROW model (at right) has motivated plan to conduct similar modeling for several USGS NAWQA study areas during 05/06

  47. USGS StreamStats • Web application StreamStats that greatly reduces the time needed to estimate streamflow statistics for ungaged sites and to make published streamflow statistics for USGS data-collection stations easily accessible • Based upon state-specific regression equations • Supports TMDLs

  48. Training and Outreach • Cross-program coordination role • Headquarters team • Regions • State/Tribal partners • On-site training to HQ, Region & State clients • On-line tutorials for applications including video! • Comprehensive technical support • waters_support@epa.gov • 1-800-844-0638

  49. Summary • WATERS framework improving • More data available, more analyses possible, with greater access • Enabling Informed Decision-Making
