The Carol Stream Dolphins is a volunteer-based program for youth who want to join the world of competitive swimming. The Dolphins compete in the DuPage Swim & Dive Conference along with 12 other park district teams during the Summer season; the competition is from June through July.  The Dolphins also compete in the Northern Illinois Swim Conference along with 14 other park district teams. During the winter season, the competition is from October through mid-March.

The team is split up into three practice groups based on swimming ability. Blue Team swimmers must have a minimum of two years prior to competitive swim experience or approval from the Head Coach to join the Blue Team and they must be able to swim 50 yards of every stroke. White Team swimmers have some experience with competitive swimming or are able to swim 50 yards of two strokes. Green Team swimmers are new to competitive swimming and must be able to swim at least 25 yards of one stroke. All swimmers are invited to participate in dual meets. Participation in Championship Meets are determined by times at the end of the dual meet season. Participants must be able to swim a minimum of 25 yards without stopping to compete in a swim meet.

In addition to team practice, Carol Stream Park District is providing weekly strokes and skills clinics. These clinics are optional and are available for per diem registration. Swimmers can focus their time on a specific skill or stroke with a low staff to swimmer ratio ensuring they get the most out of their practice time. Strokes and Skills Clinics are available for the four strokes, starts and flip turns, and sprints.

Although the swim team is a Carol Stream Park District program, the team is run in large part through the help of parent volunteers. Parents are required to volunteer at swim meets. Parent volunteers are the only way to help keep the costs of the swim team as minimal as possible. The Dolphins appreciate all of their dedicated volunteers!
