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.
115-acre reservoir offers shore & boat fishing plus multi-use paths & a large picnic shelter.

“It is nice and carm lake with beautiful sunset scenery, and a lot activities are allowed in this reservoir.”
“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.
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
