Summary

This dam serves primarily for recreational purposes and stands at a height of 38 feet with a structural height of 42 feet. With a maximum storage capacity of 140 acre-feet and a normal storage of 77 acre-feet, Dam No 3 covers a surface area of 7.1 acres.

Managed by the Kansas Department of Agriculture, Dam No 3 has a spillway width of 20 feet and a maximum discharge capacity of 676 cubic feet per second. Despite its fair condition assessment, the dam is classified as having a high hazard potential due to its proximity to populated areas. While the risk assessment is moderate, routine inspections are conducted every three years to ensure the safety of the structure and its surroundings.

Water resource and climate enthusiasts will find Dam No 3 an intriguing site for its unique design, purpose, and regulatory oversight. The dam's location along Mine Creek-TR in Worland, Missouri, offers a picturesque setting for outdoor recreation and serves as a vital component of the local water management system. As efforts continue to mitigate potential risks and enhance emergency preparedness, Dam No 3 remains a focal point for sustainable water resource management in the region.

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.
