EPA convened a technical workshop to evaluate the relationship between the low salinity zone (where marine and freshwater mix) and aquatic life populations including fish, zooplankton, and phytoplankton. Workshop products were provided to the State Water Resources Control Board to use as they consider updates to water quality standards intended to protect aquatic life. Workshop products are provided below.
