Open Water Swim
The Open Water Swim area for training purposes is located within the SCUBA Diving area. It is marked by three orange buoys that form a ¼-mile perimeter triangle. The Open Water Swim season is April 1 to Oct. 31, dawn until dusk. Swimmers will need an Aurora Reservoir day pass or annual pass to enter the park.
The SCUBA and Open Swim area is located at the far northeast part of the lake. As you enter the park look for the East Lot sign (with a SCUBA icon) and take a left. That road will take you to the east parking lot below the dam. Take the steps up to the top of the dam and go to your left to the east end of the lake. The SCUBA and Open Swim areas are marked off by buoys.
