The Little Scioto Tygarts Watershed (HUC 05090103) covers approximately 1,026 square miles of southeastern Ohio and northern West Virginia. The area is characterized by steep terrain and is drained by a number of small streams that feed into the Ohio River. The watershed is home to several important reservoirs, including Tygart Lake and the Ohio River itself, which provide drinking water and recreational opportunities for the region. The hydrology of the watershed is influenced by a number of factors, including precipitation, snowpack, and land use practices. The area receives an average of 42 inches of precipitation per year, with the majority falling during the spring and summer months. Snowpack is typically light in the region, with little accumulation outside of higher elevations. Surface water quality in the watershed is variable, with some streams showing signs of pollution from agricultural runoff and other sources. Reservoir constituents include a variety of fish species, including bass, crappie, and catfish. Climate trends in the region have been impacted by global warming, with temperatures increasing by an average of 2 degrees Fahrenheit over the past century. This has led to changes in precipitation patterns, with more frequent and intense rainfall events occurring in recent years. Despite these challenges, the Little Scioto Tygarts Watershed remains an important resource for both humans and wildlife alike.
