The Northern California Swim League (NCSL) has 26 teams and over 4,000 swimmers. To accommodate dual meets and maintain a competitive nature within the league, swim teams are arranged into five different conferences, and those are realigned on a regular basis to insure the most competitive meets possible.

For the 2019 swim season, the Fair Oaks Dolphins are part of the Motherlode Conference of the Northern California Swim League.
