In 1983, Indian Lake State Park manager Dave Helgeson realized there was a need for improvement in many areas around the lake. Having received little capital funding for many years, Dave formed a state park advisory council, comprised of community leaders, to bring attention to those needs. The council’s purpose was to inform the Indian Lake community, as well as local and state officials, of the sought-after improvements. It soon became the Indian Lake Development Corporation. The initial focus of the group was on the development of ILSP facilities, but soon expanded to include the preservation of our natural areas, and enhancement of fishing and hunting. ILDC has worked alongside the Indian Lake Watershed Project for many years, becoming a model for a successful partnership for other state parks.

Through fundraising events and donations from the community, ILDC has been able to be responsible for many projects and improvements throughout the state park. It has purchased picnic tables, park benches, playground equipment, law enforcement supplies, and much more. A rentable multi-purpose building constructed at the ILSP was partially funded by ILDC. In June of 2017, a dog park was opened at Old Field Beach. The following year, ILDC installed two shade structures at the beach, as well. An ADA compliant dock was installed at the Russells Point Harbor, across from the donut shop. ILDC is currently responsible for the maintenance of the shoreline in state park areas. On June 11th, 2022, ILDC held the grand opening of its largest project to date, the new Fox Island Playground. This playground is inclusive, and has access to an ADA compliant dock and fishing area.
