Summary

With a dam height of 13 feet and a length of 300 feet, this Earth dam plays a crucial role in managing water resources and supporting the local ecosystem. The dam is regulated by the Department of Conservation and Recreation, ensuring that it meets all necessary standards for safety and efficiency.

Despite its importance, Lilly Point Dam's hazard potential is currently labeled as "Undetermined," and its condition assessment is listed as "Not Rated." The dam has not been rated for risk assessment, and emergency preparedness measures such as an Emergency Action Plan (EAP) have not been documented. While the dam has not been inspected recently, its state-regulated status indicates a commitment to ensuring its ongoing maintenance and functionality for the benefit of the surrounding environment and community.

With a storage capacity of 243 acre-feet, Lilly Point Dam serves as a crucial water management structure in the area, impacting the tributaries of St. Peters Swamp and Cumberland Natural Area. As climate change continues to pose challenges to water resources, structures like this play a key role in maintaining biodiversity and supporting aquatic habitats. As enthusiasts for water resources and climate issues, monitoring and advocating for the proper management and maintenance of dams like Lilly Point Dam is essential to ensure their continued effectiveness and safety in the face of changing environmental conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
