The Indian Lake Watershed Association (ILWA) began as a group of concerned citizens who initially organized as the Indian Lake Improvement Association in 1978. In 1985, the group incorporated as the Indian Lake Watershed Association Inc. (ILWA), a 501c3 nonprofit organization which primarily focused on combating the affects of development within the urban watershed on water quality at Indian Lake.
The ILWA has worked for over 35 years to restore and preserve the environmental quality of Indian Lake as well as improve the neighborhood surrounding it. The ILWA also maintains two neighborhood World War II memorials and holds neighborhood cleanups focused on the shoreline of Indian and Little Indian Lakes and public spaces in the surrounding neighborhood. The ILWA works with educational partners on important research opportunities and engages in neighborhood projects throughout the entire watershed. A major element of any project the association undertakes includes educational outreach.
