The Cossayuna Lake Improvement Association (CLIA) is a 501 (c) 3 not for profit volunteer organization.  CLIA was formed in 1954 by a group of residents of the vicinity surrounding Cossayuna Lake. 

The main purpose of the early organization was to encourage social life among its members, sponsor social activities among the younger members of the community, and to promote the health and general welfare, improvement and advancement of the community as a whole.

In our continuing effort to help raise awareness regarding the vital issues surrounding the ecology and lifestyle of our lake and its surrounding area, CLIA maintains this website.
