Actions and Evaluations

Status Description
Ongoing E4. Evaluate fall pulse flows for attraction and passage benefits to chinook salmon and steelhead.
Not Addressed E3. Evaluate the effects of flow fluctuations established by the guidelines of the FERC Settlement Agreement on spawning, incubation, and rearing of chinook salmon, and if substantial adverse effects are indicated, modify guidelines to reduce effects.
Ongoing E2. Evaluate and implement actions to reduce predation on juvenile chinook salmon, including actions to isolate "ponded" sections of the river.
Ongoing E1. Identify and implement actions to provide suitable water temperatures for all life stages of chinook salmon; 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 emigration.
Not Addressed A6. Coordinate the AFRP with appropriate activities supported by the Riparian and Recreation Improvement fund that was established by the New Don Pedro Settlement Agreement.
Not Addressed A5. Establish a "streamwatch" program to increase public participation in river management.
Not Addressed A4. Support the Tuolumne River Interpretive Center.
Not Addressed A3. Screen all diversions to protect all life history stages of anadromous fish.
Ongoing A2. Improve watershed management and restore and protect instream and riparian habitat, including consideration of restoring and replenishing spawning gravel and performing an integrated evaluation of biological and geomorphic processes.
Not Addressed A1. Implement a flow schedule as specified in the terms of the FERC order resulting from the New Don Pedro Project (FERC Proceeding P-2299-024). Supplement FERC agreement flows with water acquired from willing sellers consistent with applicable guidelines or negotiate agreements as needed to improve conditions for all life history stages of chinook salmon.
