The Northern California Swim League (NCSL) was founded in 1993 with 11 original teams. In that founding year, the league had 1,711 registered swimmers. The Northern California swim league has grown to 23 teams and now has almost 5,000 swimmers. To accommodate dual meets and maintain a competitive nature within the league, we arranged into five different conferences. The conferences are realigned on a regular basis to ensure the most competitive meets possible. Mailing Address: Northern California Swim League, PO Box 601791, Sacramento, CA 95860
