Summary

The earth dam stands at a structural height of 19 feet and has a hydraulic height of 18 feet, creating a reservoir with a maximum storage capacity of 61 acre-feet. The dam is situated on McHenry Creek-OS and is managed by a private owner, with no state regulation or permitting required.

Despite being privately owned, Tall Pine Lake Dam is recognized for its significant hazard potential, warranting careful monitoring and management. The dam has not been rated for its condition assessment, and there is no established Emergency Action Plan (EAP) in place. With a spillway width of 0 feet and a maximum discharge of 15 cubic feet per second, it is essential to ensure that the dam is regularly inspected and maintained to prevent any potential risks to surrounding areas.

Water resource and climate enthusiasts visiting Tall Pine Lake Dam can appreciate the serene recreational opportunities it offers while also recognizing the importance of responsible dam operation and management. With its picturesque location and significant hazard potential, this dam serves as a reminder of the crucial role that proper infrastructure maintenance plays in ensuring the safety and well-being of surrounding communities and the environment.

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.
