Lake Doctor | A Lilly Center for Lakes and Streams Podcast

In Episode 20 of The Lake Doctor Podcast, hosts Suzie Light and Dr. Nate Bosch revisit the best moments from Season 2 episodes about wetlands. They explore how wetlands act as nature’s kidneys—filtering nutrients, reducing floodwaters, and protecting lakes from pollution—while explaining the differences between marshes, swamps, bogs, and fens.

Featuring insights from Landon Vine, Nathan Herbert, Nate Simons, Jacob Macke, and Stephen Jacquemin, the episode shows how restored wetlands filter significant amounts of water and help reduce harmful algal blooms. Nate and Suzie connect these ideas to Kosciusko County and the new Lake Rx program, highlighting why protecting and restoring wetlands is key to cleaner, healthier lakes. There will be some really big news about Lake Rx in the coming weeks, so make sure you're subscribed. You won't want to miss this announcement!

In Episode 19 of The Lake Doctor Podcast, we welcome Jacob Macke, owner of Chapman Lake Nursery and a passionate engineer-turned-native plant grower. Jacob shares his inspiring journey—after erosion threatened his new Chapman Lake home during windy storms, he discovered native plants' deep roots for shoreline stabilization. Starting with milkweed during the 2020 COVID summer, his family raised and released over 50 monarch butterflies—sparking a deep dive into native gardening.

He explains key benefits: native plants like swamp rose mallow, showy tick trefoil, and butterfly weed thrive in Indiana's soils, filter nutrients from runoff, support pollinators and wildlife, and prevent monocultures when mixed with grasses. Jacob contrasts true natives (like butterfly weed) with non-native invasives (like butterfly bush), offers tips on establishment, rabbit protection, and seed collecting, and highlights his local sales, events, and upcoming workshops at the Lilly Center. Tune in for an uplifting story of how one homeowner’s fix can serve as a blueprint for healthy lakes and thriving wildlife across Indiana.

Dive into the wild heart of northeast Indiana in this episode of The Lake Doctor Podcast, where we sit down with Nathan Herbert—a lifelong herpetology enthusiast turned Northeast Indiana Conservation Lands Manager for The Nature Conservancy. Nathan takes us on a captivating journey from his childhood days flipping rocks for snakes in Pennsylvania to his current role stewarding remarkable natural treasures.

This episode explores The Nature Conservancy's properties in Kosciusko County, including Oppenheim Woods—a 62-acre mixed hardwood forest with trees over 200 years old—and a hidden bog not open to the public due to its fragility and rarity. Nathan highlights restoration efforts, invasive species management, and the unique biodiversity of bogs and fens, including carnivorous plants, rare turtles, and rediscovered species like arrow grass. 

With tales of massasauga rattlesnakes, quaking bogs, and community weed-wrangling events, this episode sparks awe for Indiana’s wild places and shows how everyone can play a role in helping to preserve them.

In Episode 17 of The Lake Doctor Podcast, we sit down with Dr. Stephen Jacquemin, professor at Wright State University’s Lake Campus, to explore the remarkable recovery of Grand Lake St. Marys, Ohio’s largest inland lake. Once a poster child for harmful algal blooms—fueled by shallow depths and heavy nutrient runoff from surrounding agriculture—the lake hit crisis levels with toxins in the 99th percentile, impacting public health, tourism, and property values.

Stephen traces the lake’s history as a 1830s canal reservoir and shares how community-wide action turned the tide: farmers adopting precision nutrient management, cover crops, tile controls, and riparian buffers, combined with the strategic restoration of engineered wetlands now covering over 2.5% of the watershed. These wetlands filter up to 15% of incoming water, significantly reducing nitrogen and phosphorus while boosting wildlife habitat and offering recreational trails. With ongoing monitoring ensuring long-term success, the episode highlights measurable progress in toxin reduction and provides an inspiring, practical blueprint for Kosciusko County and other lakes facing similar challenges.

In this unique episode of The Lake Doctor Podcast, Dr. Nate Bosch and co-host Suzie Light have a 'behind-the-scenes' conversation about a new way of thinking about lake care. Rather than focusing on single problems or quick fixes, they introduce a holistic approach to lake health—one that views a lake as a living system. Drawing from years of applied research and on-the-ground experience, Nate and Suzie explain why understanding the full picture of a lake’s data is essential to creating lasting, meaningful improvements to a lake's health.

This podcast episode centers around the launch of Lake Rx, the new phase of the Lilly Center's work designed to provide prescriptions for lakes based on their specific conditions and needs. Much like a health plan for a person, Lake Rx uses scientific data to diagnose challenges and recommend targeted, scientifically-backed solutions that support long-term lake health. Listeners will gain insight into how this approach empowers lake residents and communities to move from reactive management to proactive stewardship—helping lakes become clean, healthy, safe, and beautiful for generations to come.

Nate and Suzie sit down with Brant Fisher, a Non-game Aquatic Biologist with the Indiana Department of Natural Resources. Brant brings a wealth of knowledge about the often-overlooked species that quietly keep Indiana’s waterways thriving—from freshwater mussels and darters to mudpuppies and rare invertebrates. He shares how these creatures act as early warning indicators for water quality and why biodiversity matters more than most people realize.

This conversation shines a light on the hidden world beneath the surface, revealing how small and unassuming species play an outsized role in the health of our aquatic ecosystems. Brant also discusses the ongoing challenges non-game species face, like the harvesting of shells for jewelry and the complexity of mussel reproduction. He offers practical steps we can take going forward to support conservation efforts. Develop a deeper level of appreciation for Indiana’s non-game aquatic life.  

Brant Fisher, originally from western Pennsylvania is a nongame aquatic biologist with the Indiana DNR. Brant monitors species that are not typically fished for sport like mussels, darters, crayfish, and freshwater jellyfish. When doing mussel surveys,  these biologists will often crawl through rivers and streams while scanning the bottom with their hands. Brant has worked at educational events in the past where he teaches about aquatic ecosystems. Brant has also collaborated with Purdue and other environmental nonprofits to support mussel restoration and research projects.

In this episode of The Lake Doctor Podcast, we dive into the inspiring story of Jace Morgan, an ultra-endurance athlete with a growing passion for environmental stewardship. Earlier this year, Jace took on an incredible challenge — swimming the entire 17-mile circumference of Lake Wawasee in his event, Lap the Lake. What started as a test of endurance quickly became a journey of purpose and connection to the very waters he calls home. With each mile, Jace developed a deeper appreciation for the natural beauty and community that surrounds our lakes and streams. From struggling with hypothermia to facing his fear of weeds (or aquatic macrophytes!), Jace's story is one of resilience and strength.

But Jace’s story doesn’t stop at the finish line. Moved by the experience and the support of his community, he has found a new passion for Lake Wawasee and partnered with the Wawasee Area Conservancy Foundation (WACF) — ensuring that future generations can enjoy the same clean, vibrant waters that fueled his swim. Join us as Jace shares what it takes to push both body and spirit beyond limits, how the lake reshaped his outlook on stewardship, and why every effort can lead to waves of lasting change.
