River lovers, science nerds, and curious minds… this one’s for you 🌊
The Winona Will Dilg Chapter of the Ikes invites you to a deep dive into what’s happening beneath the surface of the Upper Mississippi.
Join us at the Winona County Historical Society for a fascinating talk from Wisconsin Department of Natural Resources scientist Shawn Giblin.
🪶 The focus: disappearing burrowing mayflies… tiny creatures with a massive role in the river’s food web.
📉 The concern: sharp population declines over the past 15–20 years.
🧪 The science: new research is uncovering links between pesticide presence and ecosystem changes in the Upper Mississippi River.
If you fish, paddle, study, or just love the river, this is a chance to hear what the data is saying and what it might mean for the future.
Free. Open to all. Come curious.
