Summary
Standing at a height of 19 feet and a length of 430 feet, the dam has a storage capacity of 64 acre-feet and serves as a popular spot for outdoor activities in the area. With a normal storage capacity of 38 acre-feet and a drainage area of 0.45 square miles, the dam provides both recreational opportunities and contributes to the local ecosystem.
Despite its age, the condition of Shamrock Lakes Dam (Center) #1 has not been rated, and the last inspection was conducted in July 1996. The hazard potential of the dam is currently labeled as 'Undetermined', and there is no Emergency Action Plan (EAP) in place as of the latest data update in April 2021. The dam's proximity to Louisville District and Congressional District 05 in Indiana highlights its importance in terms of water resource management and climate resilience efforts.
As water resource and climate enthusiasts continue to monitor and assess the condition of Shamrock Lakes Dam (Center) #1, there is a need to prioritize its safety and maintenance to ensure the protection of surrounding communities and the preservation of its recreational value. With a focus on risk assessment, hazard mitigation, and emergency preparedness, stakeholders can work together to safeguard this vital infrastructure and promote sustainable water management practices in the region.

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.
