SALEM, OR -- Starting today there will be limited access to some state parks in Central Oregon. The boat ramp at Cove Palisades at Lake Billy Chinook and the boat ramp at Prineville Reservoir will be open. Also, pedestrians will be allowed at Pilot Butte, but not cars. Chris Havel at State Parks says not all restrooms will be open and urges visitors to stay close to home. He says if the park is crowded, go home. Havel says more state parks will be open to limited day use starting next week depending upon staffing, supplies and equipment.
