Summary

The dam stands at a height of 24 feet and has a storage capacity of 141 acre-feet. With a surface area of 11 acres and a drainage area of 300 acres, the dam offers a serene setting for outdoor enthusiasts to enjoy various water activities.

Despite being privately owned, Henpeck Hollow Dam has a high hazard potential, although its condition assessment remains unrated. The dam, primarily made of earth with a buttress core, has not undergone any state inspections or enforcement, raising concerns about its safety and regulatory compliance. Additionally, the dam lacks an Emergency Action Plan (EAP) and inundation maps, highlighting the importance of implementing proper risk management measures to ensure the safety of the surrounding community.

With its picturesque location and potential risks, Henpeck Hollow Dam presents a unique blend of recreational opportunities and concerns for water resource and climate enthusiasts. As efforts to improve dam safety and regulatory oversight continue, it is crucial for stakeholders to prioritize implementing necessary measures to mitigate potential hazards and ensure the long-term sustainability of this vital water resource in Washington County, Missouri.

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.
