Summary
Mary of The Woods (Lower) is a privately owned earth dam located in Vigo, Indiana, with a primary purpose of recreation. Completed in 1957, this dam stands at a height of 18 feet and has a storage capacity of 72 acre-feet. With a surface area of 8.35 acres and a drainage area of 0.01 square miles, this dam plays a crucial role in providing recreational opportunities for the surrounding community.
Despite its recreational value, St. Mary of The Woods (Lower) poses a high hazard potential due to its structural characteristics. The dam has not been rated for its condition assessment, and its last inspection dates back to April 1995. There are no emergency action plans or risk management measures in place for this dam, highlighting the need for increased monitoring and maintenance to ensure the safety of nearby residents and the environment.
As climate change continues to impact water resources, it is imperative that structures like St. Mary of The Woods (Lower) are regularly assessed and maintained to prevent potential hazards. With its historical significance and role in providing recreational opportunities, this dam serves as a reminder of the importance of sustainable water resource management practices in the face of a changing climate.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
