About North Lake Dam
North Lake Dam is a dam in Dallas, Texas. The dam is owned by City Of Coppell (local government). It impounds the South Fork Grapevine Creek near Irving.
The dam stands 61 feet tall and stretches 4,800 feet across, creates a reservoir covering 806 acres, has a maximum storage capacity of 16,498 acre-feet, and collects water from a drainage area of 3 square miles. Completed in 1957, the structure is well into its service life at over 50 years old.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. An emergency action plan is in place for this dam. The most recent inspection on record was 06/13/2018. That was 7 years ago, which is on the longer end for a high-hazard structure.
At 61 feet, this dam is taller than 95% of all dams in the United States.
