STATUS
Restoration actions have been limited to spawning gravel augmentation and additional water provided via 3406 b(2) and 3406 b(3). Additional work is needed to replace additional gravel lost to mining and dams as well as providing additional floodplain habitat lost to the flattening of the hydrograph.

Actions and Evaluations

Status Description
A1. Implement an interim river regulation plan that meets the following flow schedule by supplementing the 1987 agreement between USBR and CDFG, through reoperation of New Melones Dam, use of (b)(2) water, and acquisition of water from willing sellers as needed.
Complete E6. Evaluate fall pulse flows for attraction and passage benefits to chinook salmon and steelhead.
Not Addressed E5. Evaluate use of the Stanislaus River by American shad and consider increasing flows and maintaining mean daily water temperatures between 61 F and 65 F from April to June when hydrologic conditions are adequate to minimize adverse effects to water supply operations and in a manner consistent with actions to protect chinook salmon.
Not Addressed E4. Develop a carryover storage target for New Melones Reservoir to ensure Vernalis flow standards are met during the 30-day pulse flow period during the third year of a dry or critical period. This will protect at least one of three year classes of chinook salmon during emigration.
Ongoing E3. Evaluate and refine a river regulation plan that provides adequate flows to protect all life stages of anadromous fish based on water storage at New Melones Reservoir, predicted hydrologic conditions, and current aquatic habitat conditions.
Complete E2. Evaluate and implement actions to reduce predation on juvenile chinook salmon, including actions to isolate "ponded" sections of the river.
Not Addressed E1. Identify and implement actions to provide suitable water temperatures for all life stages of chinook salmon, consistent with efforts to maintain adequate flows to provide fish habitat. Establish maximum temperature objectives of 56 F from October 15 to February 15 for incubation and 65 F from April 1 to May 31 for juvenile rearing and emigration.
Not Addressed A3. Screen all diversions to protect all life history stages of anadromous fish.
Ongoing A2. Improve watershed management to restore and protect instream and riparian habitat, including consideration of restoring and replenishing spawning gravel.
