The Maquoketa watershed covers an area of approximately 1,895 square miles in northeastern Iowa. The hydrology of the watershed is characterized by numerous streams and tributaries that eventually flow into the Maquoketa River. The snowpack in the watershed varies depending on the location and elevation, with higher elevations typically receiving more snow than lower elevations. Surface water in the watershed is used for a variety of purposes, including irrigation, drinking water, and recreation. Reservoirs within the watershed contain a mix of sediment, nutrients, and organic matter. Interesting climatic facts and trends in the region include a slight increase in average temperatures over the past few decades, as well as an overall increase in precipitation. This has led to concerns about flooding in certain areas of the watershed, and efforts are underway to mitigate the impacts of extreme weather events.
