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.
STATUS AS OF: June 29 , 2007Head of
The Spring HOR barrier has been completely removed. The HOR barrier will be re-installed in the fall upon request by DFG.
Agricultural Barriers (Old River near Tracy [ORT], Middle River [MR], Grant Line Canal [GLC]):
All agricultural barriers are in place and operating normally. The MR barrier has one culvert flap gate broken and so the culvert is open. We’ll be working with the DWR construction office to get approval to use divers and schedule repairs in the near future.
Modeling was not done this week as the agricultural barriers are operating normally and no HOR barrier is in place.
This will be the last weekly update for awhile unless changes are made to the barriers fully operational status. The next update will likely be in early September when we begin changing operations to install the fall HORB and notching the ag barriers.
These weekly updates are also available for your information on our NEW!!! website:
If you know of anyone else that should be receiving this update, please let me know by email, and I'll add them to the mailing list. Thanks!
