Description

The Lake County Watershed Protection District is seeking a qualified company or firm to lead and facilitate the development of a feasibility plan for the Adobe Reservoir Surface and Groundwater Storage and Flow Enhancement. The purpose of this project is to determine the viability of modifying the Adobe Creek reservoir or dam to increase and enhance surface water storage, groundwater storage, and environmental stream flow downstream to Adobe Creek. The firm will work closely with the District staff and partner to conduct background research, field sampling and monitoring, facilitate and organize water rights packages, and conduct community outreach and host public meetings. The firm will also assist the district in draft review, presentation, and feedback incorporation for the final Plan. Key aspects of the project include: • Surface water storage of Adobe Reservoir • Groundwater storage and associated groundwater recharge • Environmental Stream flow downstream to Adobe Creek to maintain flows sufficient for mid to late season Clear Lake Hitch spawning and hatch • Collaboration with the District staff, County of Lake Water Resources Department, Big Valley Rancheria EPA Department, Big Valley Groundwater Sustainability Program Advisory Committee, FlowWest Consulting, and individual and neighboring property owners
