Watershed Hydrology

The Lower Saline Watershed (HUC 10260010) covers an area of approximately 2,547 square miles in central Arkansas. The watershed is characterized by a humid subtropical climate, with hot summers and mild winters. It is a part of the Arkansas River Basin and is fed by several smaller streams. The hydrology of the watershed is dominated by the Saline River, which runs through the heart of the region. The river is a major source of surface water for the area, and is used for both recreation and irrigation. Snowfall is rare in the Lower Saline Watershed, with only occasional winter storms bringing significant accumulation. The region is more prone to flooding, with heavy rainfall causing periodic flash floods. There are several reservoirs in the watershed, including Lake DeGray and Lake Ouachita. These reservoirs are important sources of drinking water and provide recreational opportunities for locals and visitors alike. In recent years, the Lower Saline Watershed has experienced increased frequency and severity of drought conditions, as well as increased flooding due to heavy rainfall events. Climate models predict that these trends are likely to continue in the coming decades, underscoring the importance of responsible water management practices in the region.
