Summary

This dam, with a height of 21 feet, serves multiple purposes including fire protection, stock containment, and as a small fish pond. It has a maximum storage capacity of 99 acre-feet and a normal storage capacity of 79 acre-feet, making it a valuable resource for the local community.

Situated on the South Solomon River, No 3 is classified as a buttress dam with a hydraulic height of 20 feet and a structural height of 21 feet. Despite its low hazard potential and unlisted condition assessment, the dam has not been inspected or assessed recently. It is vital that proper maintenance and monitoring of this water structure be conducted to ensure its continued safety and functionality for both water resource and climate enthusiasts in the area.

While the dam has not been modified or updated in recent years, it is crucial that emergency action plans are prepared and reviewed regularly to mitigate any potential risks associated with its operation. With its strategic location and multiple uses, No 3 plays a significant role in water conservation and management efforts in Rooks County, Kansas.

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.
