June, 2021, Lake Alum Treatment The Hess Lake Improvement Board is considering an expensive Lake Alum Treatment. See page 25, description of Alum Treatment & pages 32, 33 on cost of treatment in the 2020 Progressive AE Hess Lake Study. I read that Silver Lake near Lake Michigan is considering applying for a permit from EGLE to plant native aquatic plants. Could this be done at Hess Lake instead of an Alum Treatment? Study located under the Engineering Tab.
June, 2021, Grand Valley State University Muck Study, GVSU completed a study on Hess, Brooks & Pickerel Lake muck to determine if muck pellets actually do anything. Which they don’t work as advertised. Read the Executive Summary on Page 2 & Summary on page 34 first. The rest of the report a lot of technical data. This study is located under the Engineering Tab. Muck pellets were used in Hess Lake in years 2016, 17 & 18.
