| Data Used to Assess Water Quality: |
Resident mussles (composites (40-50 individuals) of resident Mytilus californianus) were collected by CCLEAN staff twice a year in 2002, 2003, 2004, 2005 and 2006 at two sample locations. One of the 20 composite samples exceeded the OEHHA screening value for shellfish. |

| Water Quality Objective/Criterion: |
OEHHA Screening value for the protection of human health from the consumption of fish and shellfish. Brodberg and Pollock calculated "California Lakes Screening Values" for a 70 kg adult human and based on a fish consumption value of 21 g/day (1999). OEHHA Screening Value in fish and shellfish tissue for Dieldrin is 2.0 ug/Kg. |
