1.4.1 Grassland Bypass Project Goals

In addition to the overall project purpose of removing subsurface agricultural drainage water from wetland channels, participating entities and agencies have supported the project in the expectation that it will lead to accomplishment of broader drainage management goals. The following project goals have been articulated by the team in the process of developing this monitoring plan:

Section 1.0 Introduction

The U.S. Bureau of Reclamation (USBR) signed a Finding of No Significant Impact (FONSI) No. 96-01-MP on November 3, 1995 for use of a 28-mile segment of the San Luis Drain (SLD). This segment, known as the Grassland Bypass, will convey agricultural drainage waters from the Grasslands Subarea to the San Joaquin River via a 6 mile segment of Mud Slough (north). An Environmental Assessment (EA) dated April 1991 was prepared in support of the FONSI.

CFWG Meeting

Topics discussed included recently completed studies on mercury stable isotopes and diffusive gradient thin-film devices, a wrap up of the sediment coring study, and an update on modeling work.

Statewide Bioaccumulation Monitoring

The Surface Water Ambient Monitoring Program (SWAMP) Roundtable has formed a subcommittee, the Bioaccumulation Oversight Group (BOG) that develops plans for and guides implementation of SWAMP statewide bioaccumulation monitoring. The BOG is composed of State Water Resources Control Board and Regional Water Quality Control Board staff and representatives from other agencies and organizations including USEPA, the Office of Environmental Health Hazard Assessment (OEHHA), the Department of Fish and Game (CDFG), and the San Francisco Estuary Institute (SFEI).
