State Water Resources Control Board Bay Delta Plan Update Final Draft

Dear Landowner/Water User,


On July 6, the State Water Resources Control Board announced its final draft for the Bay-Delta Plan Update for the Lower San Joaquin River and Southern Delta. This plan update addresses many issues regarding water supply and quality in the Delta, but the largest of these issues is the requirement of 30-50% of unimpaired flows from the tributaries of the San Joaquin River for the period of February through June. The State Water Resources Control Board is requesting comments on the final draft by July 27th and begin consideration of the final draft plan at its August meeting.  This has the potential of a large impact to PID operations in the coming years if adopted in its current form. Maven produced the following message regarding the announcement: THIS JUST IN … State Water Board Seeks Public Comment on Final Draft Bay-Delta Plan Update for the Lower San Joaquin River and Southern Delta

PID has partnered with its neighboring agencies to develop a plan to evaluate the impacts regarding predation of the native species in the river to determine if additional flows are necessary to help support a thriving population of listed native fish species. Furthermore, this effort to evaluate predation is in support of other activities along the Merced, Tuolumne and Stanislaus Rivers to address other factors that affect native fish mortality in the San Joaquin River and to improve conditions for a healthy population without the need to increase flows into the San Joaquin River. Patterson ID will continue to work on evaluating these impacts in the hopes that the unimpaired flow requirements may be reduced or eliminated entirely in support of other means to help address the decline in the listed native fish species.

This notice is intended to inform PID’s landowners and water users of the final draft plan by the Board and provide them an opportunity to see the proposed plan and the potential of its impacts to the Patterson Irrigation District.

2018 Winter Shutdown Notice

As a follow-up to the newsletter and growers workshop in February, this is an additional notice to growers and water users of the Patterson Irrigation District that the District will be shut down during the period of November 15, 2018 through March 1, 2019. This is to allow the District to perform the following:

  • Perform winter maintenance and repairs
  • Finalize the Schedule A Improvments of the Main Canal Rehabilitation Project, which includes executing the connections to the laterals and turnouts along the pipeline, abaondoment of Pump Stations 2 and 3, and testing of the new pump station.

This wintertime shutdown period was assessed based upon historic wintertime operations to minimize impacts for a winter irrigation water demand for the district. It should be noted, that although the District will be shut down, if the winter produces little or no rain, the District is developing a contingency plan to set in motion to at least make some water available if absolutely necessary.

SWRCB fines issued for no waste discharge permit

On Friday, April 20, 2018 the State Water Resources Control Board Issued a notice that a farming operation in Kern County was fined due to not taking out a waste discharge permit for compliance with the Irrigated Lands Program and waste discharge order for the Kern River watershed.


This notice shows the impact to growers for not complying with the irrigated lands program and also not joining a regional drainage coalition. The coalitions help offset the costs for compliance and ensure that you are in compliance with the current and any new orders.
