The Stockton Creek Preserve is a unique partnership project between Sierra Foothill Conservancy and Mariposa Public Utility District (MPUD). The Stockton Creek Preserve surrounds The Stockton Creek Reservoir and provides immediate watershed protection for the town’s primary domestic water resource. The completion of this 722-acre preserve and trail system provides viewshed conservation, recreation opportunities, and fire hazard reduction. The preserve includes a trail easement donated by the Fischer Family through their adjacent property so that the publicly accessible trails now extend from just above the Mariposa County High School to Hwy 140.
