Summary
The dam, built for recreational purposes, is an earth dam with a buttress core type and stands at a height of 15 feet. It has a storage capacity of 50 acre-feet and a spillway type classified as uncontrolled. Despite being rated as having a low hazard potential and a moderate risk assessment, the dam's condition is currently not rated.
Located on the UNT of Splunge Creek, Moore Lake Dam has not undergone recent inspections or assessments, and its emergency action plan status remains unknown. The dam's primary purpose for recreation highlights its importance in providing water resources for outdoor activities in the region. While it may not pose an immediate threat, ongoing monitoring and maintenance are essential to ensure the safety and longevity of this water resource structure in the face of changing climate conditions. Enthusiasts interested in water resource management and climate resilience can delve deeper into the unique features and regulatory aspects of Moore Lake Dam to better understand its role in the local ecosystem.

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.
