About D&r Pipeline Construct. Co Lake Dam
The primary purpose of D&r Pipeline Construct. Co Lake Dam is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by D&r Pipeline Constr Co (private). It impounds the Tr-little Sac River near Springfield.
The dam stands 25 feet tall, creates a reservoir covering 7 acres, has a maximum storage capacity of 94 acre-feet, and collects water from a drainage area of 560 square miles. Completed in 1975, 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. The most recent inspection on record was 05/15/1979. That was 46 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
