A detailed data and source assessment can be found in the Las Tablas Creek and Lake Nacimiento Total Maximum Daily Load for Mercury Draft Project Report dated September 25, 2002. This TMDL has been approved by the Central Coast Water Board in 2003. However, neither State Board nor USEPA approved this TMDL and the TMDL project has been indefinitely postponed until USEPA takes further action regarding potential superfund site. The Draft TMDL project report identifies mercury as the primary metal of concern however, nickel content of waters in the Klau Branch tributary to the South Fork Las Tablas Creek has also been found to exceed Basin Plan Water Quality Objectives. The Draft TMDL project report can be viewed here: https://www.waterboards.ca.gov/centralcoast/water_issues/programs/tmdl/docs/las_tablas_lake_naci/index.shtml |
