2. What is StreamStats? n A map-based Web application that provides information that can be used by engineers, managers, planners, and others to make informed decisions on water-related activities n Primary product is streamflow statistics

3. How is StreamStats Information Used? n Engineering Design—Bridges, culverts, flood-plain management n Water and Land Management—Water rights adjudications; water & land-use planning; in- stream flow, fish passage, & habitat studies n Water Quality Regulation—Low flows, perennial vs. intermittent streams (TMDL’s, NPDES Permits) n Design of Sampling Networks—Cover a range of desired flows

4. Development Team n USGS John Guthrie, RMMC, programmer Al Rea, ID WSC, GIS specialist Kernell Ries, OSW, hydrologist, coordinator Pete Steeves, MA WSC, GIS specialist Dave Stewart, OSW, GIS specialist n ESRI Christine Dartiguenave Dean Djokic Zichuen Ye

5. State Implementation Process n Usually funded through cooperative agreements with local agencies 1. Local USGS Water Science Centers Prepare GIS datasets Populate database of statistics for USGS gages 2. Development team sets up internal test site 3. WSC evaluates accuracy of internal test site 4. Development team and/or WSC makes any needed changes 5. Site is made available to public

6. Alabama StreamStats Cooperators n Alabama Department of Conservation and Natural Resources - Wildlife and Freshwater Fisheries n The Alabama Office of the State Climatologist n Alabama Power n Alabama Department of Economic and Community Affairs - Office of Water Resources n Alabama Department of Transportation

7. GIS Data Preparation n Data preparation and watershed characteristics measurements done using ArcHydro Data Model and Tools http://support.esri.com/index.cfm?fa=downloads.dataModels.fil teredGateway&dmid=15 http://support.esri.com/index.cfm?fa=downloads.dataModels.fil teredGateway&dmid=15 n Data for boundary delineation DEM – usually 10-m NED ( http://ned.usgs.gov ) http://ned.usgs.gov Stream network – Usually NHD ( http://nhd.usgs.gov ) http://nhd.usgs.gov Basin boundaries – Usually WBD ( http://www.ncgc.nrcs.usda.gov/products/datasets/watershed/ ) http://www.ncgc.nrcs.usda.gov/products/datasets/watershed/ DEM forced to conform with stream network and basin boundary datasets

8. StreamStats Versions n National site for data-collection stations only n “Classic” version built using ESRI’s ArcMap and ArcIMS software, with custom connectors Phased out as of late 2010 n Version 2 – based on ArcGIS Server 9.2 Released during Oct. 2008 for MA and UT Now available for all states

9. Implementation Status n 20 states fully implemented n 5 states partly implemented n 9 states in implementation process

10. National Site Capabilities Provides ability to locate any USGS streamflow data-collection station in the Nation and get: n Descriptive information about the station n Previously published basin (physical and/or climatic) characteristics n Previously published streamflow statistics n Displays digital topographic maps and aerial imagery as base map

11. “Classic” Site Capabilities n For data-collection stations, same as national site n For user-selected ungaged sites: Delineates drainage basin (watershed) boundaries Editing of basin boundaries, if necessary Computes basin characteristics Provides estimates of streamflow statistics based on regression equations Download of basin boundary shapefiles Printing of maps shown in user interface

12. Added Version 2 Capabilities n Estimates streamflow statistics for ungaged sites based on flow at nearby gages (drainage-area ratio method) n Stream network navigation n Computes NHD reach addresses for selected sites n Land surface and stream channel profiles n Traces raindrop path n Primary capabilities available as Web services

27. Summary of Benefits n StreamStats provides a set of tools that are useful for water resources planning and management, and for engineering design n StreamStats substantially reduces effort and cost compared to previous manual techniques n Network navigation allows: Estimation of flows for ungaged sites based on flows for nearby gaging stations Identification of activities upstream or downstream from selected sites and obtaining information for those activities
