  1. Franks TractPilot Project Don Kurosaka, DWR Ajay Goyal, DWR

  2. Agenda • Background Information • Pilot Project Alternatives • WQ Modeling Studies • Fish Studies • Project Schedule • Funding Options

  3. Flooded Island Feasibility Study • Identified WQ Improvement Potential • Evaluated Several Alternatives for benefits to: • Water Quality • Ecosystem • Recreation • Recommendations • Pilot Project to Confirm Benefits • Refine Alternatives

  4. Follow-on Activities • Evaluated Pilot Project Design Alternatives • Commenced Monitoring Flow and Salinity in Delta • Initiated Fisheries Studies

  5. Pilot Project Objectives • Confirm WQ Benefits • Monitor Impacts of the Project • Fisheries • Recreation • Ecology • Modify Project Operations to Minimize Impacts
