"Federal officials are now completing a big environmental study of the river restoration plan. No water can start flowing until the study is done, perhaps later this year. The timeline for the river work, under the guidance of a new "restoration administrator," extends beyond 2016.
This restorative work includes building a bypass around the Mendota Pool in western Fresno and Madera counties so migrating salmon won't get hung up on their way home. Gravel pits along the river will be filled in or isolated to protect juvenile salmon. Seasonal barriers will be installed to keep fish from getting lost near Los Banos.
After multiple revisions, the river restoration bill would authorize $88 million in federal funds over 10 years. The money would be combined with $200 million in state bond funds and additional federal dollars."
