USMS Northwest Zone

This site supports the Northwest Zone, which is one of eight USMS organizational zones (geographic regions) within the United States. Zones are further delineated into smaller regional subgroups called Local Masters Swimming Committees (LMSCs). Each LMSC is responsible for the activities within their province.

The Northwest Zone covered by this site is comprised of seven LMSCs. Visit the LMSC Info page to learn more about their respective swimming programs.

A detailed description and map (pdf) of each of the USMS Zones and the LMSCs can be found here.
