The lakes and rivers found within Oregon State Parks are open to unsupervised swimming. You are responsible for your own safety. Before you enter the water, you should judge your swimming skills against possible strong currents, cold water, underwater objects and steep drop-offs. Remember, that many of our natural bodies of water and man-made reservoirs are filled by snow runoff and remain cold year round. Please bring and wear a personal flotation device and swim with a buddy.
OPRD manages the day-use area under a lease agreement with the U.S. Department of Agriculture, Forest Service.
