What is StreamStats?
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
Primary product is streamflow statistics
How is StreamStats Information Used?
Engineering Design—Bridges, culverts, flood-plain management
Water and Land Management—Water rights adjudications; water & land-use planning; in-stream flow, fish passage, & habitat studies
Water Quality Regulation—Low flows, perennial vs. intermittent streams (TMDL’s, NPDES Permits)
Design of Sampling Networks—Cover a range of desired flows
Development Team
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
ESRI• Christine Dartiguenave• Dean Djokic• Zichuen Ye
State Implementation Process Usually funded through cooperative
agreements with local agencies1. Local USGS Water Science Centers
• Prepare GIS datasets• Populate database of statistics for USGS gages
2. Development team sets up internal test site3. WSC evaluates accuracy of internal test site4. Development team and/or WSC makes any
needed changes5. Site is made available to public

GIS Data Preparation Data preparation and watershed characteristics
measurements done using ArcHydro Data Model and Tools http://support.esri.com/index.cfm?fa=downloads.dataModels.filteredGateway&dmid=15
Data for boundary delineation• DEM – usually 10-m NED (http://ned.usgs.gov)• Stream network – Usually NHD (http://nhd.usgs.gov)• Basin boundaries – Usually WBD
(http://www.ncgc.nrcs.usda.gov/products/datasets/watershed/)• DEM forced to conform with stream network and
basin boundary datasets
StreamStats Versions
National site for data-collection stations only “Classic” version built using ESRI’s ArcMap and
ArcIMS software, with custom connectors• Phased out as of late 2010
Version 2 – based on ArcGIS Server 9.2• Released during Oct. 2008 for MA and UT
• Now available for all states
Implementation Status
20 states fully implemented
5 states partly implemented
9 states in implementation process
National Site Capabilities
Provides ability to locate any USGS streamflow data-collection station in the Nation and get:Descriptive information about the stationPreviously published basin (physical and/or climatic) characteristicsPreviously published streamflow statisticsDisplays digital topographic maps and aerial imagery as base map
“Classic” Site Capabilities
For data-collection stations, same as national site
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
Added Version 2 Capabilities
Estimates streamflow statistics for ungaged sites based on flow at nearby gages (drainage-area ratio method)
Stream network navigation Computes NHD reach addresses for selected sites Land surface and stream channel profiles Traces raindrop path Primary capabilities available as Web services

Summary of Benefits StreamStats provides a set of tools that are
useful for water resources planning and management, and for engineering design
StreamStats substantially reduces effort and cost compared to previous manual techniques
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
