  1. Improving Watershed Health using Citizen Monitoring, Bioassessment and Water Quality Data in Collaboration with State, County and Local Governments Joanne Hild Friends of Deer Creek Nevada City, California

  2. Friends of Deer Creek and the State of California Cooperative work 2000 until present: Collaboratively wrote and adhere to Quality Assurance Project Plan with State Water Resources Control Board. Includes quarterly Technical Advisory Committee and biannual Intercallibration sessions. 2000 until present: Developed benthic macroinvertebrate bioassessment and analysis with Jim Harrington, State Department of Fish and Game. 2003: State Water Resources Control Board 303(d) impaired water body listing of lower Deer Creek for pH 2005: State and FODC jointly held a Mercury Conference in Nevada City 2005-2006: Regional Water Quality Control Board trained and gave FODC 100 samples for total mercury in soil and water during storm events.

  3. 2005

  4. Mean pH 2000-2006

  5. Number of Intolerant Families 2000 - 2004 Mean

  6. 2004 Deer Creek 1850

  7. USGS Bear-Yuba Hg sampling led to 303(d) listing May et al, 1999

  8. Partnership with California Regional Quality Control Board Mercury Survey Objectives: • Determine the extent and magnitude of mercury contamination • Identify major mercury source locations for the purposes of remediation • Characterize mercury transport/streamflow relationships in order to estimate mercury loads

  9. Partnership with Regional Board: 100 water and sediment samples during storms. Partnerships with BLM and USGS: sample macroinvertebrates to determine the amount of methyl mercury getting into the food chain.

  10. Preliminary Mercury Results, 2006

  11. Current and future projects involving State, County, Local Governments Installation of storm drains within Nevada City Development of erosion Best Management Practices with Nevada City, Grass Valley, Nevada County Working with county to convert wastewater disinfection from chlorination to UV Restoration project in Nevada City park Expansion of FODC Analytical Lab Development of riparian interpretive trail on Nevada City and BLM property Work with members of Yuba-Bear Watershed Council Bacteria study in conjunction with Nevada County Environmental Health Collaboration with State on arsenic and heavy metal studies. Stressor Identification study using macroinvertebrates with State Fish and Game Writing a macroinvertebrate identification manual for groups in the State.
