What if I told you that beneath the tranquil surface of Mountain Creek Lake lies a story of industry, transformation, and resilience? Mountain Creek Lake Park sits on the southeastern and southwestern edges of this very lake.
Mountain Creek Lake is a reservoir. It is located eight miles southwest of Downtown Dallas. We are currently in the Mountain Creek area of the city. Look around. Notice we are south of SH 180, west of Spur 408, north of I-20, and east of FM 1382.
The lake’s story began in 1929. Construction started on the Mountain Creek Dam. The dam was completed in early 1937. The Dallas Power and Light Company needed a cooling reservoir for their electric power plant. Mountain Creek Lake was the answer.
Originally, the lake permit allowed for a capacity of 40000 acre-feet. By 1992, heavy siltation reduced that capacity. It went down to 22840 acre-feet. Mountain Creek drains a large area of 295 square miles.
Now, here is an interesting fact. The defunct Naval Air Station Dallas, Hensley Field, is on the northern shore. This is now an Armed Forces Reserve Center. This naval air station had an impact on the lake’s history.
In 1996, the Texas Department of State Health Services issued a ban. It was on keeping or eating fish from the lake. High contamination levels of PCBs and other toxic chemicals were found. These contaminants came from the Dallas Naval Air Station and industrial facilities. An airport factory and power plant contributed too.
The ban was lifted in 2010. However, the TDSHS still advised against eating any fish caught in the lake. But in 2017, they updated their advisory. White Crappie were now safe to eat. Channel and Flathead Catfish, Largemouth Bass, and White Bass could be eaten in limited amounts. Other fish like Common Carp, Freshwater Drum, or Smallmouth Buffalo were still unsafe.
As of the last update, women of childbearing age and children should not eat any fish from Mountain Creek Lake. Women past childbearing age and adult men have specific consumption guidelines. These guidelines depend on the type of fish.
Despite its complicated past, Mountain Creek Lake has a surface area of 2710 acres. Its maximum length is 2.75 miles. The maximum width is 2 miles. The surface elevation is 458 feet.
Mountain Creek Lake’s journey from an industrial necessity to a recreational space is a testament to nature’s ability to adapt. While its history includes environmental challenges, ongoing efforts strive to ensure a healthier future for both the lake and its visitors at Mountain Creek Lake Park.
