Description
Abstract: This document presents a description and interim findings of applied studies to reduce methyl mercury concentrations in two reservoirs [Almaden Reservoir, Guadalupe Reservoir] and one lake [Lake Almaden] in the Guadalupe River Watershed. These studies were voluntarily initiated in 2005 by the Santa Clara Valley Water District (District) as part of early implementation of actions by the District to restore these water bodies that have been identified as impaired due to mercury concentrations in fish that exceed applicable criteria. In October 2008, the Regional Water Quality Control Board (Regional Board) adopted a Total Maximum Daily Load (TMDL) for Mercury in the Guadalupe River Watershed into its San Francisco Bay Basin Water Quality Control Plan. Although this TMDL has not yet been through the entire approval process, it contains a requirement for the District to prepare this document by December 31, 2009. The District voluntarily agreed to submit this report to the Regional Board by this date. -- Executive summary.
