San Joaquin River Dissolved Oxygen TMDL
The San Joaquin River Dissolved Oxygen TMDL was adopted by the Regional Board on 27 January 2005. It has been approved by the State Water Resources Control Board (SWRCB) and the Office of Administrative Law. Final approval by U.S. EPA was received on 27 February 2007. The TMDL is a Basin Plan Amendment that includes a Control Program to reduce the amount of oxygen demanding substances and their precursors in the San Joaquin River.

- San Joaquin River Dissolved Oxygen Control Program Fact Sheet
- Draft Staff Report and Resolution R5-2015-0008
The Control Program required an evaluation of the allocations and implementation provisions once studies in the San Joaquin River watershed were completed. Staff reviewed the results of the studies and developed a draft Staff Report with recommendations for future actions to address the DO impairment.
The draft Staff Report was presented to the Regional Board during their February 5-6, 2015 Board meeting. Staff recommended that the allocations not be revised and the existing Control Program be continued. The Board concurred with staff's recommendation and approved Resolution R5-2015-0008. In addition, the Board strongly supported the continued use of aeration in the channel and staff's efforts to increase the number of stakeholders participating in funding the long-term operation and maintenance of the aeration facility.
Public Meetings and Workshops
Implementation of TMDL
- The TMDL contains a Program of Implementation, which describes actions required by those responsible for the contributing factors of the dissolved oxygen impairment, and includes actions to be taken by the Central Valley Regional Water Board to ensure completion of these requirements.
- The TMDL Control Program required oxygen demand and precursor studies to be completed to better understand the linkage between sources and downstream impacts.
- In 1999, stakeholders formed a Steering Committee and participated in the formation of the TMDL. A Technical Working Group was formed to provide a public forum for discussing and disseminating technical information. A website was developed to store all of the technical information generated during the TMDL development.
