About the CLIA

The Cossayuna Lake Improvement Association (CLIA) was formed in 1954 by a group of residents of the vicinity surrounding Cossayuna Lake. The first meeting was held on August 22nd of that year. Officers were elected, committees appointed, and various matters were discussed concerning the good and welfare of the community. Subsequently, a constitution and by-laws were adopted, and the Association was incorporated.

The main purpose of the early organization was to encourage social life among its members, promote social activities among the younger members of the community, and to promote the health and general welfare, improvement and advancement of the community. As the organization matured, the CLIA took a leading role in organizing sustained efforts to monitor and maintain the health of the lake. These efforts take the form of fundraising for annual invasive, non-native weed remediation as well as volunteer efforts to monitor water quality throughout the busy summer season.
