Bayou Pierre

Watershed Hydrology

The Bayou Pierre Watershed is located in northeastern Louisiana, covering an area of 1,968 square miles. The hydrology of the watershed is dominated by Bayou Pierre, which flows into the Ouachita River. The area experiences a humid subtropical climate with hot summers and mild winters. The region receives an average annual precipitation of 56 inches, with the majority falling in the summer months. The watershed is largely agricultural, with crops such as cotton, soybeans, corn, and rice being grown. Surface water quality is affected by agricultural runoff, as well as urban and industrial discharges. The Bayou Pierre Reservoir serves as a source of drinking water for the city of Monroe. The reservoir is also used for recreation, including boating and fishing. Snowpack is typically not a major factor in the area's hydrology, due to the relatively mild climate.
