Nutrient and suspended-sediment concentrations, flux, and yields in the Galena River, Illinois, 2019–21 Nutrient and suspended-sediment concentrations, flux, and yields in the Galena River, Illinois, 2019–21

Two stations on the Galena River in Illinois were monitored for nitrogen, phosphorus, and suspended sediment from 2019 to 2021 to determine physiochemical properties and constituent concentrations, flux, and yields. This information could aide in the management and understanding of the Galena River and the contributions from the intervening 58-square-mile study area watershed...
