Regan Lake Dam Reservoir Report
Last Updated: April 1, 2026
Regan Lake Dam, located in Vigo, Indiana, serves as a vital water resource for the surrounding area, particularly for recreational purposes.
Summary
This private-owned dam stands at a height of 25 feet, with a hydraulic height of 24.3 feet, and a length of 480 feet. It holds a storage capacity of 105 acre-feet, with a normal storage level of 44 acre-feet, and covers a surface area of 7 acres.
Despite its low hazard potential, the dam's condition assessment has been deemed poor, indicating a need for potential maintenance or rehabilitation. The last inspection in 2016 revealed this concerning state, with a risk assessment rating of high (2). With a history of inadequate conditions and a risk of potential failure, there is a pressing need for improved risk management measures to ensure the safety and reliability of Regan Lake Dam for both water resource supply and climate resilience in the region.

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.
