Project: Interior Delta Exports Effects Study

Description: Funding for this Project will be used to identify the environmental drivers influencing habitat and their effect on salmonid migration, survival, and cumulative losses. This project will yield novel and important data on the relationships between fish behavior, mortality and entrainment relative to operations of the CVP and SWP export and fish salvage facilities.

Reference Number: 3600BQ2096016

Implemented By: State Water Contractors

Objective: This project has four objectives: 1. Estimate the probability of entrainment, predation, survival and movement probabilities as a function of radial gate and CVP exports for PDAT tagged fish reaching the vicinity of the entrance to Clifton Court Forebay. 2. Estimate the probability of PDAT tagged fish moving to the CVP trash rack, moving past the CVP trash rack, and estimate predation mortality and survival as a function of CVP export rates. 3. Populate an operational tool to optimize juvenile salmonid survival through the South Delta based on CVP and SWP export facility operations. 4. Use SCHISM to model Delta hydrodynamics and velocities under different operation conditions including changes in inflow and export, including identifying areas of velocity changes associated with operational treatments and relate to fish behavior.
