Michigan Lake Water Clarity interactive mapping service (IMS) website

The U.S. Geological Survey Michigan Water Science Center and the Michigan Department of Environmental Quality Cooperative Lakes Monitoring Program, are pleased to announce the “Michigan Lake Water Clarity interactive mapping service (IMS) website for Predicted Secchi-Disk Transparency (SDT) Depths, Chlorophyll-a (Chl-a), and Trophic State Index (TSI) Values”. The IMS website shows predicted water clarity for inland lakes greater than 25 acres generated by relating Landsat satellite imagery to field data. The Predicting Water-Clarity project main webpage outlines the remote sensing project, the process by which the water clarity was predicted, a report documenting the process, a fact sheet summarizing the project with more information on SDT, Chl-a, and TSI, links to similar projects in other states, downloadable data and metadata, and references.
