The Monocacy Watershed (HUC 02070009) covers approximately 1,329 square miles in Maryland and Pennsylvania. It is a sub-basin of the Potomac River and is characterized by varied land use, including agriculture, urban development, and forested areas. The watershed is heavily influenced by precipitation and snowmelt, which can lead to high flows and flooding during certain times of the year. The area is also impacted by reservoirs and impoundments, which regulate water flow and provide drinking water for communities in the region. There are no specific snowpacks in the watershed, but winter precipitation can affect streamflow and water quality. Climate data shows that temperatures in the region have steadily increased over the past century, with more intense precipitation events occurring in recent years. Overall, the Monocacy Watershed is a complex and dynamic system that is heavily influenced by weather and human activity.
