Eagle Scout Projects - Troop 944

Since Marguerite Gahagan Nature Preserve was established in 1997, ten Eagle Scout candidates from Boy Scout Troop 944 of Roscommon have completed a variety of projects at the preserve.  These projects have improved access to the cabin and the trail system and enhanced the onsite education program.  Accomplishments at the Marguerite Gahagan Nature Preserve depend on people who love the outdoors, value the environment and realize the need to educate our youth about the natural world.  Thank you to all the Scouts, Scout leaders, Scout families and all those who have contributed time and talents to these worthy projects!​

Upper AuSable Water Quality Monitoring Project

In 2006, the Marguerite Gahagan Nature Preserve brought a number of organizations together to collect data and regularly monitor the water quality of the upper AuSable River watershed.  Volunteers collect insect specimens from the river system at six points on one day in Spring or Fall. Sites include the Mainstream, North Branch, East Branch, South Branch and the Big Creeks. Following the collection dates, teams of volunteers identify the bugs in the laboratory at Kirtland Community College. The type, quantity and variety of these macro-invertebrates are used to score the quality of the water system. Our goal is rather simple - create a baseline of data about the AuSable River's water quality that can be used now and into the future to measure impacts on the river.

The project is done in conjunction with MiCorps (Michigan Clean Water Corps) which was created by executive order by Governor Granholm in 2003 to assist the Department of Environmental Quality. Our AuSable River data goes into the MiCorps record system which is administered by the Great Lakes Commission in Ann Arbor, Michigan.

The project’s partners include: Kirtland Community College, AuSable River Restoration Committee, Anglers of the AuSable, the Mershon, Headwaters and Mason Griffith Chapters of Trout Unlimited, AuSable River Center, Roscommon County Community Foundation and Kirtland Community College Foundation.

The next sampling will be done Saturday, September 8, 2018. Meeting place for the event and details will be determined a few weeks before. Beginning in 2015, the project began an alternating sampling cycle. We now sample once a year; for odd-numbered years, it will usually take place on the first Saturday in June and for even years, the second Saturday in September.

Volunteers are the project's life blood. No experience is necessary. We will train you in collection techniques and insect identification. It is a fabulous way to learn about the river and its inhabitants or if you have expertise in this area, to teach others. And we always have food after a job well done. Contact Tom Dale at thdale@core.com to volunteer or if you have other questions about the project.
