Houghton Lakes Dredge Holes

Houghton lake contains a number of “Dredge Holes” located near the shoreline in numerous place. These “holes” date back to the 1950s and
there have been several tragic accidents over the years. Through the efforts of a local citizen group with the cooperation of Roscommon County, a map has been developed to identify these potentially dangerous areas. Thus far, 51 holes have been identified. A map is available at the township hall showing the GPS coordinates along with the approximate area and depth of each hole. There is no charge for the map. If you are staying at one of the many resorts in the township, they should have a copy of the map for review.
