Time has run out on a short-term plan to continue funding a network of sensors that monitors the water quality in Iowa's rivers and streams. Unless new funding can be secured, dozens of sensors will be taken offline next year, eliminating the ability to measure nitrate and phosphorus to see if conservation practices are working.

Chukwudum Eluchie dove head first into hydrology after spending many years of his education in aeronautics and astronautics. Eluchie joined IIHR—Hydroscience and Engineering (IIHR) in January 2024 as a post-doctoral researcher supporting two different labs — the Wang Research Group helping to understand turbulent wake flows behind naval ships to improve safety and energy efficiency, and the  Williams Erosion and Sediment Transport  Laboratory (WEST) researching scour and erosion on bridge piers to enhance infrastructure resilience. 

Nitrate from fertilizer and manure befouls countless waterways and kitchen taps across the US. But unlike other big polluters, from petroleum to plastics, Big Agriculture has largely avoided responsibility for its dirty footprint. In no state is this arguably clearer than Iowa, where the multibillion-dollar corn industrial complex of farmers, food processors, tractor makers, chemical companies, ethanol producers and their lobbyists reigns supreme.

Dubuque is implementing a $26 million pump system to mitigate flooding in the Bee Branch Watershed. The University of Iowa is testing a 1:7.5 scale model of the pump system to ensure effectiveness. The project is part of a larger flood mitigation effort and is expected to be operational by August 2027.

Matthew Kliegl felt a bit like a fish out of water when his master’s degree led him to study fish and their swimming behaviors. Kliegl embraced the opportunity to contribute to IIHR's legacy of fish passage research, helping to understand the movement of fish in the Mississippi River.  

With more than half of Dubuque’s population working or living in the Bee Branch Watershed — covering 6.5 miles and encompassing six schools, four parks and affordable housing — the city’s $28 million Bee Branch Stormwater Pumping Station Project is just as much money saved as it is money spent.
