1. 2014 OVERVIEW: National Streamgage Network Design by USGS

2. USGS Streamgage Network an effective combination to achieve high quality science based on reliable measurements and shared investment guided to meet national priorities

3. USGS Streamgaging History John Wesley Powell (USGS Director; 1881 – 1894) directed USGS to begin monitoring streamflow in the American west First USGS gage installed 1889 to monitor the Rio Grande near Embudo, New Mexico By 1895, streamflow was being monitored by USGS in 27 states/territories Most stations in 1968 = 8,320 in operation In 2012, USGS was operating 8,025 Streamgages

4. National Streamgage Network Cooperative Water Program CWP = 4,521 streamgages in 2012 (+750 interpretive studies) National Streamflow Information Program NSIP = 3,504 streamgages in 2012  8,025 total USGS active streamgages an effective combination to achieve high quality science based on reliable measurements and shared investment guided to meet national priorities

5. National Streamgage Network

6. Cooperative Water Program CWP Mission: to provide reliable, impartial, and timely information needed to understand the Nation's water resources through a program of shared efforts and funding with state, tribal, and local partners to enable decision makers to wisely manage the Nation's water resources.

7. Cooperative Water Program CWP = hydrologic data + investigative studies Program started as a 50:50 cost-share not authorized by Congress, except for specific direction in annual federal appropriations legislation Engages more than 1,500 cost-share “Cooperators” Active in every state & most territories Guided to meet national priorities

8. Cooperative Water Program CWP = hydrologic data + investigative studies Data collection by USGS maintaining high QA/QC Accessible to all without charge Consistent, Reliable & Available 24x7x365 Data & studies are limited by funding, but Cooperators are paying 2x the USGS funds – Competitive selection applying national priorities – USGS scientists get direct involvement in latest challenges – Cooperators get impartial science expertise from a national agency that has no regulatory function

9. National Streamflow Information Program (NSIP) Requested by Congress in 1998 USGS design was reviewed by NAS/NRC in 2004 NSIP was authorized by Congress in 2009 Program concept is to establish a reliable national “backbone” streamgage network to meet 5 specific, national needs and provide benchmark for monitoring by others Design = Network of 4,759 streamgages Strategic locations across America as Foundation for other streamgage networks Reliable + Continuous  Federal Funded 4,759 does not provide sufficient resolution to meet federal needs and constrain uncertainty without CWP supplement to bring national streamgage network to more than 8,000

10. National Research Council Review 2004 review of USGS design for NSIP 2007 review of USGS River Science 2009 review of USGS Water Program New science and more data are needed by federal, state, tribal, interstate and local officials to effectively manage water towards sustainable ends American water community needs a national leader in water sciences Favorable review of USGS operations, science capabilities and NSIP design

11. National Streamflow Information Program Reliable national streamgage network to meet 5 specific, national needs Design =network of 4,759 monitoring sites reliable + continuous  federal funded Actual < 75% currently operating, and 87% of those 3,504 streamgages lack reliable funding (i.e., depend on CWP Cooperators & OFAs), which defeats the intended reliability of NSIP A fully implemented NSIP would require $115 M to complete and $110 M/yr to operate

16. USGS Streamgage Network An effective combination to achieve high quality science based on reliable measurements and shared investment guided to meet national priorities Cooperative Water Program without the cost-share investment federal government would not have adequate coverage National Streamflow Information Program without reliable funding for the set of “backbone” streamgages federal government loses long-term records needed to identify trends and support interpretive science  8,025 total USGS active streamgages providing the benchmark needed by USGS and other agencies

17. Stakeholder Support Coalition Organized by ICWP with help from: – Western States Water Council – Association of State Floodplain Managers – American Society of Civil Engineers – National Water Resources Association – American Rivers – National Wildlife Federation

18. Stakeholder Support Coalition Focused effort to inform the Administration ( Interior & OMB ) and Congress 57 organizations endorsed the 2014 letters
