The Colonial Swimming League was founded in 1962 to sponsor competitive swimming among community swimming organizations in Northern Virginia; to develop a love for the sport among the swimmers involved; and to advance skills, team-work, and the principles of good sportsmanship. The objectives of the Colonial League swimming program are:
1. to foster a high level of competition by grouping teams of comparable strength in the same division, in accordance with the League team seeding procedure;
2. to develop the potential of individual swimmers of different ages and abilities by sponsoring a full summer dual meet season which concludes with divisional qualification meets and a League all-star meet;
3. to single out for distinction individual swimmers, age groups, and teams. With a view to fulfilling the aforementioned principles and objectives, the participating organizations agree to uphold present Constitution, By-Laws, and Meet Rules of the Colonial Swimming League.
