About Wildwood Lake Dam
The primary purpose of Wildwood Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Mdnr Parks & Recreation (state). It impounds the Thread Creek near Grand Blanc.
The dam stands 22 feet tall and stretches 243 feet across, creates a reservoir covering 84 acres, has a maximum storage capacity of 775 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 1961, 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. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 10/17/2018. That was 7 years ago, which is on the longer end for a high-hazard structure.
