A Statewide Vision
The TRVA is among several Voluntary Agreements being forged in Northern and Central California. These agreements seek to enhance sensitive fish species and their habitats and ensure a reliable water supply for urban and rural residents, farms, businesses and industry. These agreements represent a more progressive way of managing watersheds than current regulatory approaches and have widespread support throughout the Sacramento and San Joaquin Valleys and the San Francisco Peninsula.
TRVA Key Elements
The TRVA is designed to respond to seasonal variability and meet the life cycle needs of native fish species while protecting water supplies. The Agreement provides elevated river flows for the environment and improved habitat and predation control to support fish populations.
Expected Benefits of the TRVA
The TRVA is a comprehensive, 15-year management plan based on solid science and responsiveness to nature. It provides multiple ecosystem benefits that will enhance fish populations, while also balancing water supplies across all sectors, including the environment, cities, industries, communities and agriculture.
Science Paves the Way,
Anchored by Good Governance
The TRVA is built on best available science and decades of monitoring, data collection and multiple Tuolumne River-specific scientific studies. Under the TRVA, a new Tuolumne River Partnership will be formed to guide a spill management plan and habitat improvement program and to develop a capital fund and annual funding. The Agreement also provides flexibility and the ability to adapt quickly to changing conditions.
