The California Natural Resources Agency and the California Environmental Protection Agency released a framework for potential voluntary agreements to improve river flows and habitats in the Sacramento-San Joaquin Delta last week.

The framework, which expands on previous commitments, 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.
