The Tuscarawas watershed (HUC 05040001) covers an area of approximately 1,981 square miles in northeastern Ohio. The region is characterized by a humid continental climate with warm summers and cold winters. The area receives an average annual rainfall of 39 inches, with the majority occurring during the summer months. The watershed is home to several reservoirs, including the Portage Lakes, Lake Nimisila, and Berlin Lake, which provide drinking water to the surrounding communities. The surface water in the watershed is influenced by agriculture, urbanization, and mining activities in the region. The snowpack in the Tuscarawas watershed plays an important role in the region's hydrology. During the winter months, the snowpack accumulates in the higher elevations of the watershed and gradually melts, providing a consistent source of water for streams and rivers throughout the spring and summer. Overall, the Tuscarawas watershed faces challenges such as erosion, sedimentation, and pollution from various sources. However, efforts are being made to address these issues through improved land management practices and increased awareness of the watershed's importance.
