  1. 2006FMP SAMPLING PLANFOR ADVISORY DEVELOPMENT Margy Gassel, Robert Brodberg, Sue Roberts Office of Environmental Health Hazard Assessment California Environmental Protection Agency

  2. Key CriteriaFor SelectingSampling Sites • Historical data • Do we have enough data to develop safe eating guidelines? • Fishing activity • What are the most popular fishing locations and species?

  3. Existing Data

  4. Fishing Information • DHS conducted needs assessments and interviews with environmental & public health, agriculture, DFG, DWR, USGS, state parks, & others in 14 counties • DHS conducted focus groups, site visits, and surveys • LSAG & SC asked to provide popular fishing locations and types of fish • Fishing guides and websites; creel surveys

  5. Fishing Info

  6. Creel Data – Species

  7. Creel Data– Anglers

  8. Maps of Historical Sampling Sites

  9. Data Summary

  10. Identify Areas with High FishingActivity

  11. Developed Sampling Site Matrix • Site names & locations • Historical data • Species identified by creel data, fishers & stakeholders • Fishing pressure • Shore fishing • Comments & special considerations

  12. Sites Scored for Priority Criteria* • Data Gaps • Highest Fishing Pressure • Geographic coverage * Criteria modified slightly from last year • More fishing information • More sites with high fishing pressure

  13. Criteria [1] Elaine Quitiquit; Sherri (IITC); DHS focus group, angler survey or site visit

  14. Target Species • Primary species defined by fishers, stakeholders, DFG wardens, creel, etc. • Species previously sampled • Important for developing Safe Eating Guidelines* * Safe Eating Guidelines include species: low mercury – better options medium mercury – eat in moderation high mercury – recommend avoiding

  15. Geographic Coverage • Sacramento River from north Delta to Lake Shasta • divided into 10 regions • Creeks, sloughs, canals • Reservoirs (& associated creeks) • Other rivers • Napa River

  16. Sampling Sites – North Delta Georgiana Slough Snodgrass Slough Steamboat Slough Sutter Bypass Cross Canal Butte Creek Napa River Rice fields (crayfish)

  17. Sampling Sites – North Delta

  18. Sampling SitesSacramento River Sacramento River - West Sacramento Sacramento River near Verona Sacramento River near Knights Landing Sacramento River near Tisdale Sacramento River near Hamilton (Scotty’s) Sacramento River at Bend Bridgenear Red Bluff Sacramento River near Deschutes Road

  19. Sampling Sites Sacramento River

  20. Sampling Sites – Reservoirs Stony Gorge Reservoir East Park Reservoir Indian Valley Reservoir Bullards Bar Reservoir Lake Almanor Bucks Lake Baum Lake Lake Britton Whiskeytown Lake Shasta Lake

  21. Sampling Sites – Reservoirs

  22. 2006 Sampling Sites

  23. Anadromous Species • American shad (Spring 2006) • Feather, Sacramento & American rivers • White sturgeon • Delta & rivers (in conjunction with DFG fishery surveys and/or derbies) • Fall 2006 (& Spring 2007) • Striped bass* • Delta & rivers • Fall 2006 & Spring 2007

  24. * Striped Bass • Preserve otoliths A bone-like structure found in the inner ear of many species of fish • Use to assess time spent in freshwater or saline waters • Ocean, bay, delta, rivers • Differences in mercury accumulation?
