LK Arlington is a man-made lake located in Arlington, Texas. The lake was created in 1983 by damming up Village Creek, a tributary of the Trinity River. The lake is used primarily for flood control, water supply, and recreation. The hydrology of the lake is managed by the Trinity River Authority, which monitors the lake levels and releases water downstream as needed. The lake also serves as a habitat for a variety of aquatic species. There are several surface flow and snowpack providers in the area, including the Trinity River and the Brazos River. The lake is surrounded by agricultural lands and is used for recreational activities such as fishing, boating, and swimming.
