Summary
This earth dam, standing at a height of 30 feet, has a storage capacity of 321 acre-feet and covers a surface area of 20 acres. With a drainage area of 475 square miles, the dam is associated with TR to Batton Branch and is managed by the local government.
Despite its significant hazard potential classified as high, the condition of Clarence City Old Lake has not been rated, and there is no established emergency action plan in place. The dam's inspection frequency is currently listed as zero, indicating a potential need for increased monitoring and maintenance. While the dam has not been modified in recent years, it remains crucial to ensure the safety and functionality of this water resource for both recreation and water supply purposes.
As water resource and climate enthusiasts, the importance of monitoring and managing dams like Clarence City Old Lake is paramount in ensuring the safety and sustainability of our water systems. With its historical significance and recreational value, it is essential to prioritize the assessment and maintenance of this dam to mitigate potential risks and safeguard the surrounding community and environment from any potential hazards.

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.
