Over-Snow Vehicle Use Designation Now in Effect

January 19, 2022 - The Forest Service has designated a system of trails and areas for OSV use on the Stanislaus National Forest to provide public access and ensure the safety and enjoyment for all users.  The Over-Snow Vehicle Use Map (OSVUM) identifies where and when OSV-use is authorized to occur.

The Stanislaus National Forest OSV-use designations include:

119,104 acres of cross-country OSV use

24.7 miles of NFS OSV-use trails available for grooming

58.4 miles of un-groomed NSF OSV-use trails

Minimum snow depth requirements

The Stanislaus National Forest’s OSV-use designations were selected after a multiple-year planning and public review process to provide winter recreation and balance resource protection. The resulting OSV-use designations complete Subpart C of the Travel Management Rule. Forest Supervisor Jason Kuiken said, “It is a balancing act to meet the needs of multiple uses and ensure forest resources are protected. We listened carefully to our stakeholders to come up with a balanced approach that provides the public with motorized and non-motorized winter recreational opportunities while natural resources, including sensitive species, are preserved and maintained for future generations to enjoy.”

The OSV-use designations displayed on the OSVUM are in effect immediately. It is the sole responsibility of users to obtain the OSVUM and only operate OSVs where and under what conditions OSV-use is authorized according to the information presented on the OSVUM.   

Visitors and OSV-users can obtain an OSVUM at Stanislaus National Forest offices.  Or by clicking here Over Snow Vehicle Use Map PDF.

Forest Supervisor's Notes


Photo of Jason KuikenForest Supervisor Jason Kuiken believes there is nothing more critical to maintaining good relationships than communication. Residents, communities and ranger districts share a dedication to keeping the forest healthy, but sometimes Forest Service procedures and actions may not be clearly understood by those outside the agency. Jason is committed to engaging the community by sharing information about some of the actions being undertaken on the forest. Jason will post a series of notes highlighting some of the vital activities that go into regaining a healthy forest. Read Jason's notes.
