The Courte Oreilles Lakes Association, Inc. (COLA) is a nonprofit association chartered under the laws of the state of Wisconsin. The purposes of COLA are (1) to protect, preserve and enhance the quality of the Courte Oreilles Lakes, their shorelands and surrounding areas, while respecting the interests of property owners and the rights of the general public, and (2) to consider, study, survey and respond to issues deemed relevant by the membership of the organization. The Courte Oreilles Lakes consist of Lac Courte Oreilles and Little Lac Courte Oreilles, both located in Sawyer County, Wisconsin.

COLA has been an active organization since 1994, providing programs for improving water quality, fishing, boating, ecology, and member appreciation of our pristine environment. COLA works in close cooperation with the Town of Bass Lake, the Wisconsin DNR, the LCO Tribe, and other entities to maximize the potential of the big and little Courte Oreilles Lakes.

COLA is an organizational member of the Sawyer County Lakes Forum, the Wisconsin Association of Lakes, and the Wisonsin Wetlands Association.
