Who We Are

The Three Rivers Levee Improvement Authority (TRLIA), a joint powers agency, was established in May 2004 by the County of Yuba and Reclamation District 784 to finance and construct levee improvements in south Yuba County.

TRLIA’s mission is to provide 200-year flood protection. Four work phases were identified to achieve that goal along the Yuba, Feather, and Bear Rivers and the Western Pacific Interceptor Canal.

To date, the Feather River Levee Improvements represent the bulk of the fourth phase of work. In total, more than $405 million is being invested in flood protection improvements, approximately half of which is being paid for by the State of California.
