Data Used to Assess Water Quality: |
Five out of 12 samples exceeded the evaluation guideline. Filet composite and individual samples were collected. Species collected were brown trout, rainbow trout, chinook salmon, largemouth bass, smallmouth bass, and white catfish. Two individual samples of chinook salmon, 8 individual samples of smallmouth bass, and 1 composite of smallmouth bass exceeded the guideline (TSMP, 2002). Sample results for each species collected on the same date were averaged. This LOE re-assesses data from LOE 664 from the 2010 Integrated Report cycle to update the evaluation guideline and to average data for each species where fish were collected on the same day at the same location. |

|
Evaluation Guideline: |
The USEPA 304(a) recommended water quality criterion for concentrations of methylmercury in fish tissue of trophic level 4 fish (150 - 500 mm; fillet wet weight) is 0.20 mg/kg. Total mercury is usually analyzed for most fish studies and assumed to be 100 percent methylmercury for the purposes of risk assessment (Klasing & Brodberg 2008). The fish consumption rate of 32 grams/day is considered more protective of human health since recommendations are now to eat 1 meal a week of fish to obtain necessary Omega 3 nutrition. The fish consumption rate of 32 grams/day is also protective of wildlife, as it protects 6 out of 7 endangered species. |

This screening level assumes an average body weight of 70 kg and a consumption rate of 32 g/day for a 30 year exposure over a 70-year lifetime. This constituent is a carcinogen therefore the risk level is set to one in a million. A cooking reduction factor of 1 is applied for skin-off fillets. |

Data Used to Assess Water Quality: |
Water Board staff assessed SWAMP data for Trinity Lake (was Claire Engle Lake) to determine beneficial use support and results are as follows: 0 of 1 samples exceed the criterion for Chlordane, Total. One composite (20 fish per composite) was generated from one species: rainbow trout. Details of the compositing protocol can be found in the March 2009 report entitled: "Contaminants in Fish from California Lakes and Reservoirs: Technical Report on Year One of a Two-Year Screening Study" (SWAMP, 2009). Total chlordane was calculated as the sum of the following chlordane isomers: cis- and trans-chlordane, cis- and trans-nonachlor, and oxychlordane. |

The modified OEHHA Fish Contaminant Goal for dieldrin in fish tissue is 0.32 ppb. This screening level assumes an average body weight of 70 kg and a consumption rate of 32 g/day for a 30 year exposure over a 70-year lifetime. This constituent is a carcinogen therefore the risk level is set to one in a million. A cooking reduction factor of 1 is applied for skin-off fillets. |

Data and Information Type: |
Fish tissue analysis |
Data Used to Assess Water Quality: |
Water Board staff assessed SWAMP data for Trinity Lake (was Claire Engle Lake) to determine beneficial use support and results are as follows: 0 of 1 samples exceed the criterion for Endosulfan I. One composite (20 fish per composite) was generated from one species: rainbow trout. Details of the compositing protocol can be found in the March 2009 report entitled: "Contaminants in Fish from California Lakes and Reservoirs: Technical Report on Year One of a Two-Year Screening Study" (SWAMP, 2009). |

Water Quality Objective/Criterion: |
Water Quality Control Plan, North Coast Region (NCRWQCB 2011): No individual pesticide or combination of pesticides shall be present in concentrations that adversely affect beneficial uses. There shall be no bioaccumulation of pesticide concentrations found in bottom sediments or aquatic life. |
Objective/Criterion Reference: |
Water Quality Control Plan (Basin Plan) for the North Coast Region |
|
Evaluation Guideline: |
National Academy of Science guidelines (NAS 1972) establish a maximum total Endosulfan concentration of 100 ug/Kg (wet weight) in tissue samples for protection of aquatic life from bioaccumulation of toxic substances. |

Spatial Representation: |
Data for this line of evidence for Trinity Lake (was Claire Engle Lake) was collected at 1 monitoring site [ Trinity Lake - 106PTL209]. Samples were collected from 1 location. Individual sample locations consisted of an area within a given waterbody from which fish tissue samples were collected. The number of sample locations per waterbody was based on the overall size of the waterbody (SWAMP, 2010). Specifics of individual sampling locations can be found in the supplemental report entitled "Cruise Report for the Surface Waters Ambient Monitoring Program (SWAMP) Bioaccumulation Screening Study in California Lakes and Reservoirs, Sampling Dates: June 2007- March 2008" (SWAMP, 2008). |
Temporal Representation: |
Data was collected on a single day 8/14/2007. |
Environmental Conditions: |
Staff is not aware of any special conditions that might affect interpretation of the data. |
QAPP Information: |
Samples were collected, processed, and analyzed in accordance with the methods described in Quality Assurance Project Plan "Screening Study of Bioaccumulation in California Lakes and Reservoirs." (SWAMP, 2008). |
