The Stockton Creek Preserve is a unique partnership project between Sierra Foothill Conservancy and Mariposa Public Utility District (MPUD). The completion of this 410 acre preserve and trail system provides domestic water supply protection, viewshed conservation, recreation opportunities, and fire hazard reduction. SFC worked in partnership with MPUD to develop the project and complete the 410 acre Stockton Creek Preserve with the county agency in December 2011. MPUD will now own and manage the property for its public benefits in perpetuity. SFC and MPUD are very thankful to the Sierra Nevada Conservancy for providing the funding for this now publicly accessible Preserve. Click here for a map to the Preserve

The Stockton Creek Preserve surrounds The Stockton Creek Reservoir, provides immediate watershed protection for the town’s primary domestic water resource. The Mariposa High School track team has been training on the property for years and they can now do so freely as the Preserve is open to the public. Visitors, residents, and students can enjoy a hike just on the edge of town on the network of trails on the preserve. 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 MCHS to Hwy 140.

MPUD will be implement fuels reduction and vegetation restoration projects to reduce the significant fire hazard that the property poses and prevent impacting the town’s water quality. MPUD’s projects provide management and mitigation of extensive damage to the SCP’s native vegetation. A previous vegetation management treatment in 2000 left a major fuel load on the property. In 2004 a fire spread from Mariposa to the property. Due to the legacy of fire suppression and fuel load on the property, the burn devastated native vegetation and precipitated a more homogenous re-growth of chaparral. The following runoff period resulted in more than double the amount of “naturally” occurring contaminants in the town’s water supply, resulting in a violation of the Federal Drinking Water Disinfection Byproduct Rule for a year. MPUD’s management of The Stockton Creek Preserve Management Project works towards restoring the native plant community and reducing the possibility of these kinds of catastrophic wildland fire effects and negative impacts to Mariposa’s water supply.
