Ivanhoe Plantation Dam

About Ivanhoe Plantation Dam

The primary purpose of Ivanhoe Plantation Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Groton Land Company Inc;ivanhoe Plantation (private). It impounds the Dry Gall Branch.

The dam stands 13 feet tall, creates a reservoir covering 29 acres, and has a maximum storage capacity of 199 acre-feet. Completed in 1974, 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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 10/16/2024.
