About Lake Arlington Dam
The primary purpose of Lake Arlington Dam is water supply. The dam stores water for municipal, industrial, or agricultural use, helping ensure a reliable supply for the surrounding area. The dam is owned by City Of Arlington (local government). It impounds the Village Creek near Arlington.
The dam stands 99 feet tall and stretches 6,482 feet across, creates a reservoir covering 1,926 acres, has a maximum storage capacity of 130,000 acre-feet, and collects water from a drainage area of 143 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 12/11/2018. That was 7 years ago, which is on the longer end for a high-hazard structure.
At 99 feet, this dam is taller than 98% of all dams in the United States.
