The Little Muskingum Middle Island Watershed (HUC 05030201) covers an area of approximately 225 square miles in southeastern Ohio. The hydrology of this watershed is characterized by small streams and tributaries that flow into the Muskingum River, which is part of the Ohio River Basin. The watershed receives an average of 40 inches of precipitation per year, with the majority falling as rain in the summer months. Snowpack is typically light and melts quickly due to the relatively mild winter temperatures in the area. Surface water quality in the watershed is largely influenced by agricultural activities, as well as residential and commercial development. Reservoirs in the area contain constituents such as sediment and nutrients, which can impact water quality over time. Interesting climatic facts and trends in the watershed include a general increase in precipitation over the past several decades, as well as an increase in the frequency of extreme weather events such as floods and droughts.
