Actions and Evaluations
| Status | Description |
|---|---|
| Not Addressed | E7. Identify, evaluate the need for, and, if needed, attempt to maintain adequate flows for migration of steelhead, consistent with efforts to maintain adequate flows for chinook salmon. |
| Not Addressed | E6. Evaluate the potential to develop and implement a strategy of coordinating a variety of specific actions, such as coincident pulse flows on San Joaquin tributaries, reduced Delta exports, hatchery releases, and gravel cleaning to stimulate outmigration and reduce predation and entrainment. |
| Not Addressed | E5. Identify and attempt to implement actions that will maintain mean daily water temperatures between 61 F and 65 F for at least one month from April 1 to June 30 for American shad, consistent with actions to protect chinook salmon and steelhead and when hydrologic conditions are adequate to minimize adverse effects to water supply operations. |
| Ongoing | E4. Identify and attempt to maintain adequate flows for migration, spawning, incubation and rearing of white sturgeon and green sturgeon from February to May, consistent with actions to protect chinook salmon and steelhead and when hydrologic conditions are adequate to minimize adverse effects to water supply operations. |
| Not Addressed | E3. Identify and implement actions to reduce predation on juvenile chinook salmon. |
| Ongoing | E2. Identify and implement actions to maintain suitable water temperatures or minimize length of exposure to unsuitable water temperatures for all life stages of chinook salmon in the San Joaquin River and Delta. |
| Ongoing | E1. Identify and implement actions to improve watershed management to restore and protect instream and riparian habitat. |
| Not Addressed | A6. Establish a basin-wide conjunctive water use program. |
| Ongoing | A5. Maintain the 6 mg/L dissolved oxygen standard during September through November in the San Joaquin River between Turner Cut and Stockton, as described in the SWRCB's 1995 Water Quality Control Plan. |
| Ongoing | A4. Reduce or eliminate entrainment of juvenile chinook salmon at smaller riparian pumps and diversions on the mainstem San Joaquin River. |
| Ongoing | A3. Reduce or eliminate entrainment of juvenile chinook salmon at Banta-Carbona, West Stanislaus, Patterson, and El Soyo diversions by implementing the Anadromous Fish Screen Program in conjunction with other programs. |
| Not Addressed | A2. Develop an equitable, integrated San Joaquin Basin plan that will meet outflow:export objectives identified under Sacramento-San Joaquin Delta Operational Target 4 and Supplemental Actions Requiring Water 7, 8, and 9. |
| Not Addressed | A1. Coordinate with CDFG and others and acquire water from willing sellers consistent with applicable guidelines as needed to implement a flow schedule that improves conditions for all life stages of San Joaquin chinook salmon migrating through, or rearing in, the lower San Joaquin River. |
