Program to Meet Standards

To facilitate effective management of salt discharges into the Lower San Joaquin River, Reclamation provides near real-time forecasts of river flow and salinity at three key locations: Vernalis, Crows Landing, and Maze Road Bridge sites where water quality objectives have been established by the Central Valley Regional Water Quality Control Board.

As part of the PTMS, Reclamation generates daily 14-day forecasts using two models. The data intensive, physically based Watershed Analysis Risk Management Framework (WARMF) model simulates both flow and salinity but takes more time to run, whereas Reclamation's Regression model which makes salinity forecasts based on measured flow at the compliance monitoring stations obtained from the California-Nevada River Forecast Center (CNRFC) runs faster and occasionally produces more reliable results. The outputs from both models are reviewed and the most reliable forecast according to the Reclamation forecast analysts is published daily on the Reclamation website.

You can access these forecasts through the links provided in the left navigation bar.
