Hello, David Buoy!

"David Buoy" is a monitoring buoy that was constructed by the U of M  St. Anthony Falls Laboratory and was deployed in the Mill Pond in New London, MN on Thursday, May 23rd, 2024 by St. Anthony Falls Laboratory staff and Middle Fork Crow River Watershed District staff. 

He will remain floating there collecting wind speed, rainfall and water quality factors including: temperature, dissolved oxygen, hydrogen sulfide, pH and more.  Data collected, combined with sediment core sampling at various sites along the river, will help determine how much oxygen remains in the water at any given time.  Low oxygen levels contribute to increased hydogen sulfide in the water, resulting in the rotten egg smell that occurs when the ice on the Mill Pond melts in early spring releasing the gasses into the air.
