Service Description

Come and swim with BAM in the open water on a special volunteer lifeguarded and protected course at the Rez during the morning wake-free hours. Each lap is about 1000 yards with shorter options. Perfect for endurance swimmers, triathletes, fitness swimmers, and beginners. Whether you are a pro triathlete or just want to get comfortable swimming in open water, we welcome you to join us through the summer. Gate opens at 6 AM, check in starts 6:15, last chance to enter water is 7:20, and you must be out of the water by 7:40. Contact us to volunteer, and you will receive a free swim for each time you volunteer. BAM members and drop-ins welcome, 18+ only. Your fee or pass does not include gate entry to Boulder Reservoir, which must be paid separately when you arrive. For safety purposes, Open Water Waiver must be signed, including current emergency contact and vehicle information, prior to your first time swimming each summer. You must check in at the registration table before entering the water every time, and you must check out at the registration table before leaving the reservoir.
