The Muskegon Watershed (HUC 04060102) covers approximately 2,745 square miles in western Michigan, including portions of Muskegon, Newaygo, and Oceana counties. It is a part of the Great Lakes Basin and drains into Lake Michigan. The hydrology of the watershed is influenced by a variety of factors, including topography, precipitation patterns, and land use. Snowpack during the winter months contributes significantly to the surface water supply in the spring. The watershed contains several large reservoirs, including the Hardy, Croton, and Hesperia reservoirs, which are used for hydroelectric power generation and recreation. Interesting climatic facts include the potential for severe weather events such as thunderstorms and tornadoes, which can result in flash flooding and other types of water damage. Over the past several decades, there has been a trend towards warmer temperatures and more frequent extreme weather events in the region.
