Prineville Reservoir State Park
Prineville Reservoir State Park, Prineville, OR
Prineville, OR
A still desert lake below rimrock canyon walls, and Oregon's very first Dark Sky Park, where the Milky Way reflects across the water.
Prineville Reservoir is a long, calm lake tucked into the high desert of Central Oregon, cradled in a canyon of juniper trees, sagebrush, and reddish rimrock walls. The lake formed in the mid-twentieth century when a dam was built across the Crooked River, holding back mountain water that flows down from the nearby Ochoco Mountains. The result is miles of quiet shoreline where the desert meets the water, a favorite of anglers, campers, and boaters looking to escape the crowds.
The park earned a special place in Oregon history in 2021, when it became the state's very first certified Dark Sky Park. Far enough from Bend and Prineville to escape their glow, the reservoir sits under a sky thick with stars. On a clear summer night the Milky Way arches overhead and reflects across the still water, and meteor showers streak above the lake. Between the fishing by day and the stargazing by night, Prineville Reservoir gives a road tripper two very different reasons to stay the night.
What Guests Love
- A calm desert lake ringed by rimrock walls and open sagebrush country
- Year-round fishing for trout and bass, from a boat or right off the shore

Worth Knowing

- Fishing is a year-round draw, with some of the biggest trout caught in the cooler months
- As Oregon's first Dark Sky Park, it shines brightest on a night near a new moon, so plan around the moon phase

Learn about Prineville Reservoir State Park
A lake in the high desert
Prineville Reservoir sits in the dry, open country of Central Oregon, where junipers and sagebrush dot the hills and low cliffs of reddish rock, called rimrock, edge the canyons. The lake was created when a dam held back the Crooked River, part of a mid-century project to store water for farms downstream, control floods, and support fish and wildlife. Filling a former canyon, the reservoir now stretches for miles with a long, winding shoreline.
That shoreline is the heart of the park. A main day-use area and campground anchor one end, with more boat ramps, primitive campsites, and quiet coves scattered along the water. The high-desert setting means big skies, warm sunny days, and cool nights, with the smell of juniper and sage on the breeze.
Fishing and camping on the water
Prineville is well known among Oregon anglers as a year-round fishing lake. Rainbow trout are the main draw, along with bass, catfish, and other fish, and the cooler months often bring up the biggest trout, whether you cast from a boat or right off the bank. The steady fishing keeps regulars coming back through every season.
Camping puts you right on the water, where you can fall asleep to the quiet lapping of the lake and wake to sun rising over the rimrock. Boaters and paddlers spread out across a lake big enough to explore for hours, and the swimming areas make a welcome cool-down on hot summer afternoons. Because the park is a fair drive from town, nights here are genuinely still and dark.
Oregon's first Dark Sky Park
Stargazers rate how dark a sky is on a scale from 1 to 9 called the Bortle scale, where a bright city glows at 9 and the darkest wild places score near the bottom. Prineville Reservoir rates near the top for darkness, about as dark as the sky gets, which is why it was named Oregon's very first Dark Sky Park in 2021. That designation recognizes both the natural darkness and the park's work to keep its own lights low and shielded.
On a clear night the reward is a sky full of stars, with the glowing band of the Milky Way, our own galaxy seen edge-on, stretching overhead. Camp along the water and the whole show reflects across the still lake, doubling it. The darkest nights come near a new moon, and summer often brings meteor showers streaking above the reservoir. All you need is a blanket and a little patience for your eyes to adjust.
