The following report on the Temporary Barriers Project is for your information and action, as appropriate.  This report will be transmitted whenever changes occur to the operation of the barriers, and as a result of modeling and/or field monitoring of water levels in the south Delta.

Water Levels and Water Quality Notifications:
No exceedance of the water quality turbidity measurements were observed. DWR will continue to monitor the water quality and water levels before, during and after the installation of the temporary barriers.
