Actions and Evaluations
| Status | Description |
|---|---|
| A11. Develop and implement a program for restoring and replenishing spawning gravel, where appropriate, in the Sacramento River. | |
| Ongoing | E9. Identify the extent of entrainment of juvenile sturgeon at diversions and pumps and minimize entrainment, if substantial. |
| Ongoing | E8. Identify and implement actions that will maintain mean daily water temperatures between 61°F and 65°F for at lease one month between April 1 and June 30 for American shad spawning below RBDD, 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 | E7. Identify and attempt to maintain adequate flows from April to June for spawning, incubation, and rearing of 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. |
| Complete | E6. Identify and attempt to maintain adequate flows for white sturgeon and green sturgeon from February to May for spawning, emigration, egg incubation and rearing, consistent with actions to protect chinook salmon and steelhead and when hydrologic conditions are adequate to minimize adverse effects to water supply operations. |
| Complete | E5. Identify opportunities for restoring riparian forests in channelized sections of the upper mainstem Sacramento River that are appropriate with flood control and other water management constraints. |
| Not Addressed | E4. Evaluate the contribution of large woody debris and boulders in the upper mainstem Sacramento River to salmonid production and rearing habitat quality. |
| Not Addressed | E3. Continue the evaluation to identify solutions to passage at RBDD, including measures to improve passage when the RBDD gates are in the raised position from September 15 through at least May 14. |
| Not Addressed | E2. Evaluate opportunities to incorporate flows to restore riparian vegetation from Keswick Dam to Verona that are consistent with the overall river regulation plan. |
| Ongoing | E11. Determine the effects of poaching and fishing on the number of spawning sturgeon. |
| Ongoing | E10. Identify green sturgeon spawning sites and evaluate the availability, adequacy and use by adult sturgeon. |
| Complete | E1. Continue study to refine a river regulation program, consistent with SB 1086, that balances fish habitats with the flow regime and addresses temperatures, flushing flows, attraction flows, emigration, channel and riparian corridor maintenance. |
| Ongoing | A9. Pursue opportunities, consistent with efforts conducted pursuant to Senate Bill 1086 (SB 1086), to create a meander belt from Keswick Dam to Colusa to recruit gravel and large woody debris, to moderate temperatures and to enhance nutrient input. |
| Not Addressed | A8. Remedy water quality problems from toxic discharges associated with Iron Mountain Mine and water quality problems associated with metal sludges in Keswick Reservoir, consistent with the Comprehensive Environmental Response, Compensation, and Liability Act and the Clean Water Act. |
| Complete | A7. Implement structural and operational modifications to the Glenn-Colusa Irrigation District’s (GCID) water diversion facility to minimize impingement and entrainment of juvenile salmon. |
| Ongoing | E2. Evaluate whether enhancement of water temperature control via shutter configuration and present management of the cold water pool at New Bullards Bar Dam is effective, and modify the water release outlets at Englebright Dam if enhancement of water temperature control via shutter configuration is effective. |
| Not Addressed | A6. Continue to implement the Anadromous Fish Screen Program. |
| Complete | A5. Construct an escape channel for trapped adult chinook salmon and steelhead from the Keswick Dam stilling basin to the Sacramento River, as designed by NMFS and USBR. |
| Complete | A4. Continue to raise the gates of the Red Bluff Diversion Dam (RBDD) for a minimum duration from September 15 through at least May 14 to protect adult and juvenile chinook salmon migrations, consistent with the 1993 biological opinion for winter-run chinook salmon and with SWRCB Order 90-5, and accommodate water delivery using appropriate pumping facilities. |
| Complete | A3. Continue to maintain water temperatures at or below 56°F from Keswick Dam to Bend Bridge to the extent controllable, consistent with the 1993 biological opinion for winter-run chinook salmon and with SWRCB Order 90-5. |
| Complete | A2. Implement a schedule for flow changes that avoids, to the extent controllable, dewatering redds and isolating or stranding juvenile anadromous salmonids, consistent with SWRCB Order 90-5. |
| Complete | A10. Implement operational modifications to Anderson-Cottonwood Irrigation District’s (ACID) diversion dam to eliminate passage and stranding problems for chinook salmon and steelhead adults and early life stages; eliminate toxic discharges from the canal and implement structural modifications to improve the strength of the fish screens. |
| Complete | A1. Implement a river flow regulation plan that balances carryover storage needs with instream flow needs consistent with the 1993 biological opinion for winter-run chinook salmon based on runoff and storage conditions, including the following minimum recommended flows at Keswick and Red Bluff Diversion dams. |
