Mountain Creek Lake

Mountain Creek Lake is a reservoir located 8 miles southwest of Downtown Dallas, Texas, United States, in the Mountain Creek area of the city. It is located south of SH 180, west of Spur 408, north of I-20, and east of FM 1382. The defunct Naval Air Station Dallas, now an Armed Forces Reserve Center, is located on the northern shore of the lake. Mountain Creek Lake Park is on the lake's southeastern and southwestern edges.

The Texas Department of State Health Services in April 1996 issued a ban on keeping or eating fish due to high contamination levels of PCBs and other toxic chemicals. The ban was lifted in 2010, but TDSHS advised against consuming any fish caught in the lake. Contaminants entered the lake from the Dallas Naval Air Station and industrial facilities such as an airport factory and power plant.
