The Lower Arkansas Maumelle Watershed encompasses approximately 1,202 square miles and is located in central Arkansas. The hydrology of the watershed is primarily influenced by the Arkansas River, which is the main source of surface water. The area experiences a humid subtropical climate, with hot summers and mild winters. Snowfall is rare but possible during the winter months. The watershed contains several reservoirs, including Lake Maumelle, which is the primary drinking water source for the city of Little Rock. The reservoirs contain various constituents, including sediment, nutrients, and pollutants, which can impact water quality. The watershed has experienced increasing urbanization, leading to changes in land use practices and increased runoff. Additionally, the area has seen an increase in extreme weather events, including heavy rainfall and flooding. Efforts are being made to mitigate these impacts through conservation and restoration projects.
