The Cuyahoga watershed (HUC 04110002) covers an area of approximately 1,464 square miles in northeastern Ohio, with the Cuyahoga River being the main waterway. The watershed has a humid continental climate with an average annual precipitation of 39 inches, which contributes to the river's flow. The area experiences significant snowfall during the winter months, with an average snowpack of 40 inches. The watershed also contains several reservoirs that are used for drinking water, irrigation, and recreational purposes. These reservoirs have been found to contain various constituents, including sediment, nutrients, and metals, which can impact water quality. Over the past few decades, efforts have been made to improve the water quality in the Cuyahoga River and its watershed through restoration projects and regulations. Despite these efforts, the area still faces challenges such as urbanization and climate change, which can impact the hydrology and ecology of the watershed.
