Colonial Swim League
The Holy Mackerels are a member of the Colonial Swim League (CSL). The CSL was created in 1962. It is comprised of over 20 area swim teams grouped in four divisions: Red, White, Blue, and Gold. Annually, these teams are placed in a seeding order based on a number of factors, including last year’s record, number of “All-Stars,” performances at the All-Star meet, and a computer-generated “time in water” evaluation of best times from the previous season.
The CSL operates under USA Swimming, which is the national governing body for the sport of swimming in the United States.
