  1. RESSED THE NATIONAL RESERVOIR SEDIMENTATION DATABASE Annual Tri-Agency Coordination Meeting Memphis, TN November 17, 2009 Mark E. Smith, mesmith@usgs.gov USGS Central Region Science Office, Denver, CO On behalf of John R. Gray, jrgray@usgs.gov USGS Office of Surface Water, Reston, VA

  2. RESSED FEDERAL INTERAGENCY SUBCOMMITTEE ON SEDIMENTATION John R. Gray, jrgray@usgs.gov USGS Office of Surface Water, Reston, VA with Jerry M. Bernard, NRCS; David W. Stewart, Gregory E. Schwarz, and Karen T. Ray, USGS http://ida.water.usgs.gov/ressed/

  3. RESSED – Subcommittee on Sedimentation Presentation Overview • RESSED – Unfunded Work in Progress • RESSED History (yes, it is relevant) • Description of RESSED Database and Website* • RESSED issues/problems • Future – RESSED-II? • *But not much in way of findings!

  4. RESSED – Subcommittee on Sedimentation But First – a Word from Our Sponsor: ACWI’s Subcommittee on Sedimentation • SOS – top national level committee for coordinating • national or organization-specific sedimentation issues • Formed ~1939, now under the Advisory Committee on • Water Information (ACWI; http://acwi.gov/) • Since ~2004, Gov’t and non-Gov’t • Members: ARS, ASCE, CUAHSI, BLM, CWRRI (CSU), • FHWA, FS, NCED, NOAA, NPS, NRCS, OSM, USBR, • UCOWR, USACE, USEPA, USGS (RESSED workgroup)

  5. RESSED – Subcommittee on Sedimentation What Is RESSED? • MS-ACCESS database and website containing sequentially measured reservoir capacities. • Changes in capacities are computed from these • data (+/- acre feet/year) • 1,824 reservoirs, 6,618 surveys: lower US (1in PR) • Based on Soil Conservation Service Form 34 (1953) • Presumed to be largest such database for US (?)

  6. RESSED – Subcommittee on Sedimentation What Is RESSED? (cont) • Clickable reservoir location info via interface • Not yet any on-line analytical capability; • Access database downloadable in entirety • Website seeks metadata on additional surveys • and/or additional reservoirs, but not updatable • Culmination of ~1.5 decades quest…! • “It’s the best we have” – Jerry Bernard, 2009 • “But a long way to go” – Gray et al., 9/16/2009

  7. RESSED – Subcommittee on Sedimentation Some History • SCS Form 34 developed in 1953 • Results published in at least 3 summary reports: • through 1953; through 1975; 1981-1985 • 1980’s: SCS attempts to develop RESIS database • (Dennis Erinakes’ oversight) • 1993: An unmarked magnetic tape is found in a • box by NRCS – presumably Erinakes’ results

  8. RESSED – Subcommittee on Sedimentation Some History (cont) • 1994: Jay Atwood, NRCS, places these data in Prelude and • Informix database formats – RESIS • 1997: Jerry Bernard: “Someone Please Give RESSED a Home!” • ~1997: Bob Stallard and David Mixon, USGS, as part of research on • global carbon budget, convert Atwood’s product to Microsoft • Access format as RESIS-II • ~2004: Eric Sundquist and Kate Ackerman, USGS, obtain Stallard • Access database and provide make improvements, also as RESIS-II • 2008-09: Subcommittee on Sedimentation (SoS) updated ~1,500 reservoir coordinates in RESIS-II, adds a reservoir as a test case, places online as RESSED

  9. RESSED – Subcommittee on Sedimentation And The Point Is??? • RESSED was not – ever – populated directly from SCS Form 34 • SCS Form 34 has 47 entries (2-page); RESSED has ~325 fields • SOS has identified the origin of values in most but not all ~325 fields • Reverse engineering required to identify all RESSED fields • We’re finding inconsistencies in this regard • Comment fields are important but currently not electronically useful • Other “warts” described later…but take it on faith… • RESSED is a Work…In…Progress.

  14. RESSED – Subcommittee on Sedimentation

  15. RESSED – Subcommittee on Sedimentation SELECTED RESSED DATABASE CHARACTERISTICS

  16. 1,824 RESSED Reservoir Locations (2009) Puerto Rico – 1 reservoir (information 9/9/2009 D.W. Stewart)

  17. RESSED Reservoir Surveys by Year 95% of surveys: 1930-1990

  18. RESSED Reservoir Capacities by Acre-Feet Classes (320) (331) (273) ~Half <10,000 Acre Feet (205) Number of Reservoirs (121) (86) (24) 1k – 10k 10 -100 .05 - 10 10k – 100k 1,000k – 1 mill 100k – 1,000k 1 mill – 29.8 mill Acre-feet

  19. RESSED Reservoir Capacities 1,360/1,824 reservoirs

  20. Number of Reservoir Surveys in RESSED* * Caveat – probably not all surveys!

  21. RESSED Years Between First & Last Surveys ~78%: first-to-last surveys: 5-30 years (1,128/1,442 reservoirs)

  22. RESSED Annualized % Capacity Loss ~82%: <2% capacity loss/year (1,124/1,365 reservoirs)

  23. RESSED Total % Capacity Loss ~32% have lost 10-30% capacity (432/1,365 reservoirs)

  24. RESSED – Subcommittee on Sedimentation Other RESSED Issues • Have yet to develop a data-entry form for SCS Form 34 (in progress*) • SCS Form 34 is but one of many data formats that now exist • - Bureau of Reclamation e-Form 34 • - Corps 2008 Reservoirs Data Call format • - On-line reservoir information from Maryland, elsewhere • GPS, depth sounders, other instrumentation provide a wealth of new • types of information, much of which needs to be stored • Quality assurance protocols have special data-storage requirements • Current RESSED isn’t amenable to the long haul *FilemakerPro Front End

  25. RESSED – Subcommittee on Sedimentation Other RESSED Issues (cont) • Let’s do a little math: • -1,824 reservoirs in RESSED • - ~81,000 dams (ergo reservoirs?) in the National Inventory of Dams (COE) • - ~?6 million – 9 million impoundments in the U.S. (USGS • National Hydrography Dataset; Renwick, Miami of Ohio) • Hence, the number of reservoirs in RESSED are: • - ~2% of number of dams in the NID (but not all cross-listed) • - ~0.03% of U.S. impoundments • RESSED reservoirs are much less than the “tip of the iceberg!”

  26. RESSED – Subcommittee on Sedimentation Other RESSED Issues (cont) American Society of Civil Engineers USA Infrastructure Report Card, February 2009 * But presumably nationally reliable statistics on other categories

  27. RESSED – Subcommittee on Sedimentation So…. • THE NATION NEEDS A CAREFULLY DESIGNED AND FULLY POPULATED NATIONAL “RESSED-FUTURE” • UNRESTRICTED ACCESS/USE • LINKED TO OTHER KEY DATABASES (NID, ETC) • UPDATABLE • CAPABLE OF STORING ALL RELEVANT DATA • ANALYZABLE LOCAL, REGIONAL, NATIONAL SCALES • BUILD IT AND THEY WILL COME

  28. RESSED – Subcommittee on Sedimentation RESSED-FUTURE • Subcommittee on Sedimentation Organized Program with wide • participation in public and private sector • Three Workgroups under SOS RESSED Committee, form in 2009 • - Data types and uses workgroup • - Data architecture workgroup • - Data-collection protocols workgroup • Must develop a base-funded, long-term project • How long can the Nation afford NOT to know the status and trends in the capacities of it’s reservoirs?!

  29. RESSED – Subcommittee on Sedimentation Take Home Message • RESSED on-line, useful tool – best we’ve got? • Work in Progress • Short Term: Need update capability, report production, other information • Long Term: 1. Need base-funded project 2. Need data types & requirements statement 3. Need new database architecture • Interested in helping….?

  30. Provide insights/suggestions/offers to help Join a Subcommittee on Sediment workgroup For that matter, join the SOS! Locate and forward data jrgray@usgs.gov jerry.bernard@wdc.usda.gov Scratch Our Back – We Scratch Yours RESSED – Subcommittee on Sedimentation
