The Little Calumet-Galien watershed is located in Indiana and Michigan, covering an area of approximately 1,770 square miles. The watershed includes 3 main rivers, the Little Calumet River, the Galien River, and the Trail Creek, and is home to several wetlands and lakes. The hydrology of the area is impacted by both groundwater and surface water, with snowmelt and rainfall contributing to the flow of the rivers. The watershed is also home to several reservoirs, including the Pine and Stone Lakes, which are important sources of drinking water for the region. Climatic trends in the area include increasing temperatures, more intense rain events, and a decrease in snowfall. These changes have the potential to impact water availability and quality in the watershed, as well as the health of aquatic ecosystems.
