Summary
This private-owned Earth dam, with a height of 25 feet and a storage capacity of 40 acre-feet, serves as a reservoir for the surrounding area. Despite its low hazard potential and not having a regulated status, the dam plays a crucial role in providing water resources for the community.
The dam, constructed with a buttress core type, has not been rated for its condition assessment, and its emergency action plan (EAP) status remains unspecified. However, with its primary purpose of recreation, the dam offers a picturesque setting surrounded by a surface area of 3 acres and drainage area of 20 square miles. While details about its completion year and modification history are unknown, the dam continues to be a significant resource for the local community.
Although not under federal jurisdiction, Holmes Lake Dam serves as a valuable asset for water enthusiasts and climate advocates. With its idyllic location and essential function in providing both recreational opportunities and water supply, the dam stands as an unassuming yet crucial structure in the landscape of Worth, Missouri.

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.
