By Suha Augenstein, 2025 Watershed Science and Outreach Intern
As part of the Glen Lake Association’s (GLA) conservation efforts, a combination of innovative technology and community effort is helping preserve the watershed’s underwater plants and wildlife. One of the most advanced techniques used is an aerial drone paired with an RTK (Real-Time Kinematic) system, to provide highly accurate GPS positioning. This methodology created the first-ever GPS-tagged biological map of the watershed and supported the GLA’s early detection of 570 square feet of EWM last year. To date, that mapping project has recorded 536 aquatic life observations across 38 species, including aquatic plants, both native and invasive, as well as fish, invertebrates, sponges, and bryozoans.
The process includes flying an RTK equipped drone above the lake to guide an underwater ROV (Remote Operated Vehicle) to densely plant populations where invasive species like the Eurasian watermilfoil (EWM) are most likely to be found. The data collected is used to guide targeted removal efforts and inform management actions, ensuring the lake remains healthy and thriving. By following standardized protocols from state programs, this ongoing work helps protect the lake’s ecosystem for future generations. It’s a perfect example of how technology, teamwork, and proactive conservation can keep Glen Lake’s waters clear and vibrant.
As this intern on this project, I had the opportunity to play an important role in the mapping process. My responsibilities included taking detailed notes at each location, documenting essential weather conditions, and recording the exact time when the drones began and stopped their flights. I also helped support the drone and ROV operations closely.
While the ROV operator focused on capturing data, I kept an eye on the live-stream video monitor to assist in ensuring that nothing was missed, noting any potential areas that needed a closer look. This experience gave me a unique insight into the precision and coordination required to effectively monitor and protect such an important ecosystem. Being part of this effort was both rewarding and eye-opening, and it showed me how important community involvement and cutting-edge technology are in environmental conservation.
About the GLA’s Internship Program
The GLA Watershed Science and Outreach Internship is an eight-week, hands-on learning experience where interns engage directly in field research, environmental monitoring, community outreach, and communications. This year, Suha Augenstein is the 2025 Watershed Science and Outreach Intern.
Our internship program began in 2017 and is made possible by generous annual donations from Jim and Susan Dutmers, Tom and Monica Dutmers, and Bill and Rita Witler, in honor of their mothers, Patricia Johnson Dutmers and Elva Witler. We are so grateful for their support.
