To deal with the reorganization and consolidation of high schools across Northern Indiana, an organizational meeting for the formation of the Northern Lakes Conference was held on February 3, 1963. Charter members of the NLC were the high schools of Bremen, Manchester, Nappanee, Plymouth, Rochester and Warsaw. The conference began competition in 1964–65 in Boys’ Baseball, Football, Basketball and Track. In 1965, Boys’ Tennis and Golf were added; Cross-Country was added in 1966; and Wrestling became a conference sport in 1968. The conference was “intended to provide good, clean competition and fellowship for the boys, the coaches, and the school bodies of the Northern Lakes region.”

Concord High School joined the NLC in 1967 and Wawasee High School joined in 1968. By 1970, all schools participated in all eight boys’ sports.

In the 1970s Girls’ sports were added. Conference competition began in 1976–77 in Basketball, Tennis, Track and Volleyball. In 1980 Swimming was added; Cross-Country was added in 1986, Softball in 1987; Golf in 1994; and Soccer in 1997.

Additional sports added to NLC Boys’ competition included Swimming in 1980 and Soccer in 1994.

Membership in the Northern Lakes Conference has fluctuated between six and eight schools throughout conference history. In 1976, Manchester changed conferences. 1987 and 1989, Rochester and Bremen withdrew memberships to begin competition with schools of lesser size and less travel than those of the NLC membership. Additions to the Northern Lakes Conference were Goshen in 1976 and Northridge in 1987. Elkhart Memorial began competition in winter sports in 2000 and all other sports in 2001–02.

The Northern Lakes Conference is recognized as one of the athletic conferences in the state of Indiana. Competitions at the state level include NLC student athletes in most every sport.^{[clarification needed]} The NLC started offering a formal coaching education course in 1991.
