U.S. Geological Survery and/or Cooperative Lakes Monitoring Program volunteer measurements (run by the Michigan Department of Natural Resources and Environment and the Michigan Lakes and Streams Association) were related to Landsat 5 TM satellite data to produce regression equations that predict Trophic State Index Values for open water areas within Michigan inland lakes greater than 20 acres if the satellite imagery was free of clouds, cloud shadows, haze, shoreline, and dense vegetation. One value is available per lake reflective of the deeper open water area. Purpose: Developed to predict Secchi-disk transparency and Trophic State Index values for Michigan inland lakes.
