California’s Natural Resources and Environmental Protection agencies late Thursday shared a framework for potential voluntary agreements to improve river flows and habitat to help recover salmon and other native fish in the Sacramento-San Joaquin Delta and its key watersheds. The framework outlines a 15-year program that would provide substantial new flows for the environment to help recover fish populations, create 60,000 acres of new and restored habitat, and generate more than $5 billion in new funding for environmental improvements and science.
