  1. Lower Truckee River Bioassessment Symposium Kathy Sertic Bureau of Water Quality Planning Nevada Division of Environmental Protection January 5, 2009

  2. Bureau of Water Quality Planning ~ Truckee River Basin Activities ~ • Monitoring • Water Quality Standards • Total Maximum Daily Loads • Bioassessment

  3. ~ Truckee River Basin Monitoring ~ • Main stem—DRI and TMWRF • Tributary streams • Evans, Dry, Thomas, Brown, Whites, Galena, Ophir, Franktown, Winters, Steamboat, Lagomarsino Creeks • Truckee River Snapshot Day • Memorandum of Understanding • Directive ofLegislative Oversight Committee for Western Regional Water Commission • Develop coordinated monitoring plan • Make data accessible to public

  4. ~ Truckee River Basin Water Quality Standards ~ • 2008NAC Reorganization • Dismantled Class Waters format • Established separate table for each waterbody • Establish/Revise standards for tributary streams • Evans, Dry, Thomas, Brown, Winters Galena, Ophir, Franktown, Steamboat, Lagomarsino Creeks • Potentially revise select TR WQS

  5. ~ Truckee River Basin Total Maximum Daily Loads ~ • 3rd party review of existing N & P TMDLs initiated by Reno, Sparks, Washoe County and Truckee Meadows Water Authority • Workplan to guide process being developed by 3rd parties, NDEP and USEPA • Extensive stakeholder input

  6. ~ BWQP Bioassessment Program ~ • Program started in 2000 to collect data to better evaluate aquatic life beneficial use attainment • Initiated in Truckee, Carson and Tahoe Basins • Ramped up by 2003 to 300+ sites statewide • Collected macroinvertebrates and limited physical habitat measurements using EPA/California Riffle Protocols

  7. ~ BWQP Bioassessment Program ~ • In 2005 began using Multi-Habitat Monitoring Protocols • Consistent with EPA National Rivers and Stream Assessment Protocols and revised California Protocols • Reach length = 40x wetted width • 11 transects within each reach • Collect • Macroinvertebrates • Periphyton • Water chemistry • Sediment metals • Fish at some sites • Expanded physical habitat parameters

  8. ~ Truckee River Basin Bioassessment Program ~ • Established Sites • Above Verdi (2005 & 2008) • Below Verdi • Patagonia (2005 & 2008) • McCarran Bridge • Lockwood (2005 & 2008) • Painted Rock • Below Tracy-Clark (2005 & 2008) • PLPT Reservation • 2005/2008 used Multi-Habitat Monitoring Protocols at select sites (limited p-hab) • Continue to monitor current sites and incorporate historic sites if possible

  9. ~ Truckee River Basin Bioassessment Program ~ • In 2005 developed Indices of Biological Integrity (IBIs) • Macroinvertebrates (Tetra Tech) • Periphyton (Desert Research Institute) • Fish (Dynamac Inc.) • 2007 Recalibration of Macroinvertebrate IBI by Tetra Tech for the Truckee, Carson and Walker Rivers

  10. ~ Truckee River Basin Bioassessment Program ~ • Evaluate potential of using the Observed/Expected Macroinvertebrate Model (RIVPACS) in combination with the Macro IBI • Coordinate with USEPA, PLPT and other agencies to conduct a Stressor Identification Case Study using the Causal Analysis Diagnosis Decision Support System or CADDIS

  11. ~ Truckee River Basin Bioassessment Program ~ • Coordinate with PLPT and other agencies on a pilot project to develop and test a Tiered Aquatic Life Use Model • Extend knowledge obtained and tools developed from all these Truckee River projects to other river basins in Nevada

  12. ~ Bureau of Water Quality Planning Truckee River Activities ~ • Commend all the local, state and federal agencies and other entities working to address the multitude of environmental issues that exist in the Truckee Rive Basin • We look forward to continuing and completing these collaborative efforts to improve water quality and watershed health for all uses and users of the Truckee River
