Confirmed from Lagerman Reservoir's own listing, the park or land manager's website, and runner reviews. Blank cells mean we could not verify that fact — we would rather say "not reported" than invent one. There is no Easy / Moderate / Hard rating on this page on purpose: a one-word difficulty score tells you nothing about whether a trail suits your run. Surface, distance, shade and hours do.

🌾 quiet & peaceful 6 mentions

“Great, quiet little body of water for paddle boarding!”

I came here at early sunset time. The view was far beyond my expectation and imagination. So calm and peaceful to comfort me. Next time I will arrange more time to take a longer walk.

Love this spot out here. Beautiful and quite love the sunsetI got quite a few beautiful pictures. There are restrooms there usually feel sanitized, they have parking plenty of it and they also have little trails you can walk, I would definitely recommend going and having fun with your family.

It is nice and carm lake with beautiful sunset scenery, and a lot activities are allowed in this reservoir. There are toilets, picnic table,even a grill there, but it is pitty the grill was locked when I visited there.

★★★★☆ — John , Jul 2025

Quiet place for a nice walk or picnic. Many birds around the area. Happened to see a couple of bald eagles and Hawks. Good for running too. There is a longer 5 mile loop nearby that can be a good long run

Trail conditions & character

What this trail is actually like underfoot and overhead, taken from its own listing and from reviews. Each one links to every other trail with the same character. Busy or quiet is reported as a plain fact, not a plus or a minus — a runner heading out alone at dawn often wants company on the path, and someone running intervals wants an empty one.

  • SurfaceCrushed gravel — the rail-trail classic: softer than asphalt, still smooth enough for tempo work
  • DistanceNot reported. Trail systems often quote total path mileage rather than a single loop, so measure the route you actually want before you drive out.
  • ShadeNot reported. Assume some of it is exposed and carry water in summer.
  • At the trailheadparking, restrooms — reported by runners
  • DogsWelcome, per reviewers. Leash rules vary by park — the trailhead sign is the authority.
  • Stroller / wheelchairReported as smooth and step-free enough for a running stroller or a chair.
