Lake Doctor | A Lilly Center for Lakes and Streams Podcast

Curious about what makes Indiana's lakes tick? Join us as we chat with Tyler Delauder, the District Fisheries Biologist from the Indiana Department of Natural Resources. Tyler shares his fascinating journey from aspiring teacher to passionate steward of Indiana’s aquatic ecosystems. Learn how a summer internship transformed his career path and fuelled his personal love for fishing and outdoor adventures, a passion he now shares with his family. Dive into the DNR's essential work in maintaining our lakes, particularly through the Status and Trends project, a key initiative that ensures the health and quality of lakes across Indiana.
Ever wondered what's really happening beneath the surface of your favorite fishing spot? Tyler breaks down the intricate food chains within lake ecosystems, from the top predators like bass and northern pike to the vital roles of zooplankton and phytoplankton. He gives practical advice for local anglers, highlighting the best fishing spots in Kosciusko County and stressing the importance of adhering to fish consumption advisories for safety. You'll also gain insights into Indiana’s fishing regulations and where to find critical information on mercury advisories, especially for lakes like Winona Lake.
But it's not all smooth sailing in Indiana's lakes. Tyler delves into the battle against invasive aquatic species, focusing on a troublemaker known as "starry." Discover the pros and cons of different management strategies, from herbicide treatments to mechanical removal, and learn why timely fish kill reporting is crucial. We also explore ongoing research on the impact of public sewer systems on lake health and efforts to clear log jams from the Tippecanoe River.
