The Maple Watershed covers an area of approximately 1,121 square miles in southwestern Wisconsin. The hydrology of the watershed is characterized by numerous streams and tributaries that ultimately discharge into the Mississippi River. The region experiences a continental climate, with warm summers and cold winters. The Maple Watershed receives an average of 32 inches of precipitation annually, with snowfall accounting for approximately 30% of the total. The snowpack in the watershed typically forms in late November and persists through early April, with average depths ranging from 20-30 inches. Surface water quality is generally good, with low levels of pollutants and minimal human impact. There are several reservoirs located within the watershed, including the Blackhawk Lake and Millville dams. There is a trend towards increased precipitation in the region, which may have implications for water management and flood control in the future.
