The Huron Vermilion Watershed spans over 1,100 square miles, covering parts of Michigan and Ohio. It is a part of the larger Maumee River Basin, which ultimately flows into Lake Erie. The hydrology of the watershed is heavily influenced by precipitation, which is highest during the summer months. Snowpack in the watershed can also have a significant impact on water quality and quantity. The surface water in the watershed is primarily comprised of streams, rivers, and wetlands. The reservoirs in the watershed contain various constituents, including sediment, dissolved oxygen, and nutrients. Interesting climatic facts include the occurrence of lake-effect snow in the region, which can result in significant snowfall during the winter months. Trends in the watershed include increasing urbanization, leading to increased runoff and potential water quality issues. Conservation efforts are underway to protect and preserve the watershed's natural resources.
