The Upper Calcasieu Watershed (HUC 08080203) covers an area of approximately 1,300 square miles in southwestern Louisiana, USA. The watershed is characterized by a humid subtropical climate with hot summers and mild winters. The region receives an average of 60 inches of rainfall annually, and there is a significant amount of surface water in the area. The Calcasieu River is the main river in the watershed and supports a variety of aquatic species. The area also experiences occasional snowfall, although it is not common. There are a few small reservoirs in the watershed which serve as water sources for nearby communities. The water quality in the watershed is generally good, although there are some concerns regarding nutrient pollution from agricultural activities. In recent years, the region has experienced an increase in the frequency and intensity of extreme weather events, including flooding and drought. This trend is likely linked to climate change and underscores the importance of carefully managing the watershed to ensure its long-term health and resilience.
