The Old Time Bluegrass Festival has been held each year as a benefit for the Anderson Marsh Interpretive Association (AMIA), a non-profit organization dedicated to protecting and supporting Anderson Marsh State Historic Park.

Due to California’s budget crisis, Anderson Marsh State Historic Park is among the state parks scheduled to close on July 1, 2012.

AMIA is negotiating an agreement with the State of California to operate the Park on a limited basis. This will ensure that the public will continue to have access to the Park and that AMIA activities such as guided nature walks, school field trips and tours of the historic Ranch House and Barn complex will continue.
