Freshwater Science: Visualizing Water Quality Trends in the Lake Erie Watershed

June 10, 2026 – New research from Ohio Sea Grant, Stone Lab, and the Harmful Algal Bloom Research Initiative

Water quality in the Western Lake Erie watershed can change daily, yet puzzling trends—like an unexpectedly low or high phosphorus concentration in key tributaries—raise important questions for scientists and managers to address. Understanding both short-and long-term trends in phosphorus concentrations is important because phosphorus drives harmful algal blooms and directly affects the health of Lake Erie.

With Harmful Algal Bloom Research Initiative (HABRI) funding, researcher Nate Manning of Heidelberg University and his team are addressing this challenge by combining high frequency water chemistry and sensor data from across Ohio creeks and rivers, analyzing trends, and launching a new interactive data dashboard that makes decades of monitoring data easier for anyone interested to explore, download, and use.

The webinar is free, but registration is required to receive log-in information.

About the Speaker
