The Indian Lake State Park Nature Center Programs are sponsored jointly by the Indian Lake Watershed Project and OSU Extension-Logan County


Indian Lake has faced two major problems:

  1. The lake lost 35% of its original depth because of sediment. Sediment comes into the lake from wind and water soil erosion. To prevent the erosion many farmers along the four major arteries feeding Indian Lake (North fork of the Miami River, South fork of the Miami River, Blackhawk Creek, and Vanhorn Run) use the no-till method of farming. This method cuts the crops off at the ground leaving the roots to hold the soil in place. Crews, monitoring how deep the sediment is, estimate a reduction from 80,000 tons of sediment to 10-13 tons today.
  2. The second problem was to improve the nutrients in the lake for wild life habitat. If you saw the lake 16 years ago you would describe the color as brown. The healthy green color we observe today is due to the efforts of the Indian Lake Development Corporation, The “clams”, a citizens group that do voluntary water clarity checks, and the Indian Lake State Park Rangers.
