Project: Cache Creek Studies Basin-Mercury Characterization and Control Study

Description: The RWQCB adopted the Total Maximum Daily Loads for the control of methyl and total mercury within the State's Flood Control System. The Department has significant responsibility for monitoring, evaluating and reducing total and methyl mercury loads passing through the Flood Control System and into the Yolo Bypass and the Delta. The Department is conducting characterization and control studies for activities, including flood control improvements and modifications, and wetland mitigation work with the potential to affect total and methyl mercury concentrations within the State's Flood Control System.
