Regional Board Conclusion: Region 2 data was not included in the 2012 Integrated Report so all decisions are carried over from the 2010 listing cycle.
 
Regional Board Decision Recommendation: After review of the available data and information, RWQCB staff concludes that the water body-pollutant combination should be placed on the section 303(d) list because applicable water quality standards are exceeded and a pollutant contributes to or causes the problem.
 
State Board Staff Review of Regional Board Conclusion and Recommendation:
 
State Board Decision Recommendation: After review of this Regional Board decision, SWRCB staff recommend the decision be approved by the State Board.

Data and Information Type: Fish tissue analysis
Data Used to Assess Water Quality: Six out of 11 samples exceeded. A total of 11 composite samples were collected and analyzed from Lake Chabot - 3 black crappie, 1 channel catfish, 3 largemouth bass, and 3 goldfish. Three goldfish and two largemouth bass samples exceeded the guideline (TSMP, 2002).
Data Reference: Placeholder reference 2006 303(d)
 
SWAMP Data: Non-SWAMP
 
Water Quality Objective/Criterion: San Francisco Bay RWQCB Basin Plan: Many pollutants can accumulate on particles, in sediment, or bioaccumulate in fish and other aquatic organisms. Controllable water quality factors shall not cause a detrimental increase in concentrations of toxic substances found in bottom sediments or aquatic life. Effects on aquatic organisms, wildlife, and human health will be considered.

Data and Information Type: Fish tissue analysis
Data Used to Assess Water Quality: Fish were collected for tissue analysis at one location from Lake Chabot (Alameda Co). A total of 13 sample composites were generated from two species: Largemouth Bass (11) and Common Carp (2). 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). A total of 12 out of 13 samples exceeded the OHHEA fish tissue screening value for human health.

Water Quality Objective/Criterion: The Basin Plan contains the following objective: Many pollutants can accumulate on particles, in sediment, or bioaccumulate in fish and other aquatic organisms. Controllable water quality factors shall not cause a detrimental increase in concentrations of toxic substances found in bottom sediments or aquatic life. Effects on aquatic organisms, wildlife, and human health will be considered.

Spatial Representation: Samples were collected from one location in Lake Chabot (Alameda Co). As discussed in the Lakes and Reservoirs Report (SWAMP, 2009), individual sample locations consisted of an area within a given waterbody with an approximate one-mile diameter, from which multiple fish tissue samples were collected. The number of sample locations per waterbody was based on the overall size of the waterbody. 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). Data collected from this waterbody was assigned under Station Name "Lake Chabot (San Leandro)_BOG" in the SWAMP report.
Temporal Representation: Samples were collected on July 31, 2007
Environmental Conditions: There are no known environmental conditions (e.g., seasonality, land use practices, fire events, storms, etc.) that are related to these 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).
