The tribes and environmental groups submitted a petition to the State Water Resources Control Board demanding the state change its approach and adopt science-based standards that ensure adequate flows in the Delta to improve water quality and sustain imperiled fish, including species that are at risk of extinction.

They said the ecological crisis in the Delta has its roots in California’s history of violence against Native people, the taking of land from tribes and structural racism that shaped how the water rights system was established more than a century ago. They said deteriorating conditions in the estuary represent a “continuation of California’s discriminatory water management history.”

They wrote in their 169-page petition that the state water board’s “failure to adopt sufficiently protective water quality standards entrenches a discriminatory system of water rights that was founded on the dispossession of Indigenous Californians and exclusion of communities of color, and that continues to prioritize large-scale agricultural interests over those of vulnerable Californians living in the Delta.”
