Fishlake National Forest

The agency’s national route data maps 2,165 miles of road and 1,181 miles of motorized trail open to vehicles on this forest. Below is what each class of vehicle may use, and where that data runs out.

The figures, from the agency’s own data

What each vehicle class can use

These are miles where the Motor Vehicle Use Map affirmatively designates the class as open. A blank value in the source data means the class is not designated on that segment. It is not the same as a closure, and no closed figure is published here because the data cannot support one.

Vehicle class	Road miles	Trail miles	Total
ATV	2,086	1,171	3,257

What the national data holds for this forest

The national dataset holds route records for every ranger district on this forest.

Ranger district	Road records	On the map	Motorized trail records	On the map
Richfield Ranger District	700	700	604	302
Fillmore Ranger District	484	484	474	237
Fremont River Ranger District	657	657	284	139
Beaver Ranger District	464	464	224	111

Counts are records in the USDA Forest Service Enterprise Data Warehouse MVUM service, roads and trails layers, harvested 21 August 2026. “On the map” means the record carries geometry a map can draw. A district with no road records is not a district without roads; it is one the agency has not published to this dataset.

Why a route with no mapped location matters

A route on this forest is legal to drive only if it is on the forest’s Motor Vehicle Use Map. Every route the Forest Service designates gets a recorded length in its database; only some get a location anyone can pull up. A route with no location can’t be looked up in that data, can’t be proved legal from it, and can be left off the next map without anyone noticing. The proposal would make that next map the legal record.

1,192 miles of motorized trail on this forest, trails designated for ATVs, dirt bikes or side-by-sides, have no mapped location in the agency's national route data. Those routes are in the agency's route database with a length and, in many cases, live vehicle-class designations, but no location, so no map built on that data can show them. That is 50 percent of this forest's recorded motorized trail mileage. It is a count of that national data, which the proposal would make the legal record, and not an audit of this forest's own printed map.

This map is being rewritten, and comment is open

On 24 August 2026 the Forest Service proposed rewriting 36 CFR parts 212 and 261, the rules that produced this map. Today a route on the Fishlake National Forest is closed to vehicles unless the forest studied it and put it on the map. The proposal flips that: open unless someone documents a reason to close it. It also removes the national rules that tell a forest supervisor to weigh damage to soil, water and wildlife, and conflict with other visitors, before a route goes in.

That change lands here in a specific way. The proposal would also make digital maps the authoritative source for what is designated, and 1,192 miles of this forest's motorized trail have no mapped location in that data at all. A route with no location is a route that’s hard to defend, hard to prove you may ride, and easy for the next map to leave out.

Public comment ran through docket FS-2026-0100 on regulations.gov until 23 September 2026. Comments that name a forest and say what the writer knows about it are the ones the agency has to answer. You know this one.

Method. Figures for Fishlake National Forest from the USDA Forest Service Enterprise Data Warehouse MVUM service, layers 1 and 2, harvested 21 August 2026. "Mapped" miles are measured from published geometry. "Recorded" miles come from the agency's route-length attribute and exist whether or not the route has been digitized. The two are different measures and are never added together. This page is not a legal travel document; the official MVUM for this forest is.
