Hydrological and Water Rights Technical Analysis

The contract entails conducting detailed hydrological modeling and technical analysis to evaluate instream flow requirements and the impacts of water diversions on aquatic ecosystems, with the goal of supporting the reallocation of water resources to benefit fish and wildlife. This work will involve assessing current water rights, flow dynamics, and environmental needs to provide scientifically grounded recommendations for improving ecological conditions through adjusted water management practices. The technical analysis must integrate data on hydrology, water rights history, and ecological thresholds to ensure that any proposed reallocations are both legally defensible and ecologically effective. The work is being performed as a subcontract under the authority of the California State Water Resources Control Board, Division of Water Rights, and is classified under NAICS code 541690 for other scientific and technical consulting services. The project is scheduled for a June 2026 posting date, indicating it is in the planning phase with anticipated execution in the near future. Performance will occur within California, focusing on water systems impacted by diversions that affect native fish populations and riparian habitats. The outcome of this effort is expected to directly inform policy and regulatory decisions related to water allocation and environmental protection in the state.
