Streamgaging Task ForcePlan
1. Identify goals of a national network 2. Compile information on all streamgaging stations3. Evaluate achievement of goals using USGS
network model4. Identify additional stations needed to achieve each
goal 5. Estimate cost of new or upgraded stations6. Recommend a long-term funding strategy7. Submit final report by December 31, 2000

Streamgaging Task ForceNetwork Goals
1. NWS and NRCS forecast points*2. NFIP communities3. Key river basins*4. River basin compacts and decrees*5. Major river crossings of state, tribal, and
international boundaries*6. Representative streams and rivers for flow
estimation and long-term trends*7. River reaches with impaired water quality

Streamgaging Task ForceNetwork Goals
8. Rivers with point-source discharge permits 9. Inflow and outflow of major reservoirs10. Major rivers with diversions11. Rivers draining Federal lands12. Rivers with significant canoeing, kayaking and
rafting13. Rivers supporting migratory fish populations14. Rivers used for commercial navigation

Meta data required for adding stations to network model
• Station code• Station name• Latitude/longitude• Drainage area• Years of active record• Availability of telemetry• Data quality• Funding

USGS Network ModelUSGS Network Model
• Conterminous U.S.• 60,000 streams (total 1M kilometers)• 329 river basins and 2,200 watersheds• 18,000 NFIP communities• 303(d) file of impaired reaches• NPDES permits• Reservoir inventory• Whitewater inventory• Water use by county and HUC• 20,000 streamflow stations
– 7,000 USGS active– 1,800 other stations

Priority for Additional Stations
• Upgrade existing stations operated by other organizations– Stage-Q rating– Telemetry– Serve data on the internet
• Reactivate discontinued stations
• Build new stations

Long-term Funding Strategy
• USGS provide data processing and dissemination infrastructure
• USGS support and operate critical Federal stations
• OFAs support other Federal interests• States and USGS support stations that have
both a Federal and State/local interest• States support local-interest stations
