Data Used to Assess Water Quality: |
Fish were sampled for tissue analysis at one location from this reach. A total of 4 out of 8 samples exceeded the USEPA fish tissue criterion for human health. The average wet weight mercury concentration in fish tissue was 0.35 ppm for all 8 samples collected. The number of fish collected per sample, the measured mercury concentrations in fish tissue, and the number of exceedances are, by species: Rainbow Trout- 1 sample, 0.02 ppm, no exceedances; Sacramento Pikeminnow- 1 sample, 0.46 ppm, 1 exceedance; Sacramento Sucker- 2 samples, 0.22 and 0.38 ppm, 1 exceedance; Smallmouth Bass- 4 samples, 0.26-0.72 ppm (average 0.43 ppm), 2 exceedances. All 8 composite samples were collected from fish with average total lengths greater than 150 mm, which represent fish most commonly caught and consumed by sport fishers and their families. |

|
Water Quality Objective/Criterion: |
All waters shall be maintained free of toxic substances in concentrations that produce detrimental physiological responses in human, plant, animal, or aquatic life. The objective applies regardless of whether the toxicity is caused by a single substance or the interactive effect of multiple substances. |
Objective/Criterion Reference: |

|
Evaluation Guideline: |
The USEPA Fish Tissue Residue Criterion for methylmercury in fish is 0.3 mg/kg (0.3 ppm) for the protection of human health. This is the concentration in fish tissue that should not be exceeded based on a total fish and shellfish consumption-weighted rate of 0.0175 kg fish/day. |

Data Used to Assess Water Quality: |
A total of 30 water samples were collected at one location from this reach representing sixteen 30-day average samples. None of the sixteen 30-day average samples exceeded the USEPA (CTR) mercury-based numeric criterion for human health. The total recoverable mercury concentrations in water ranged from 0.74 ng/l to 7.4 ng/l with an average of 2.8 ng/l for the sixteen 30-day average samples. |
