Summary

Completed with a height of 22 feet and a length of 1600 feet, this dam has a storage capacity of 516 acre-feet and serves a drainage area of 1.93 square miles. The spillway, with a width of 40 feet, is uncontrolled, and the dam has a low hazard potential rating.

Located in the Kansas City District, Dd No 101 is regulated by the Kansas Department of Agriculture and meets state permitting, inspection, and enforcement requirements. Although the condition assessment is not rated, the dam has a moderate risk assessment rating of 3. Emergency action plans and inundation maps have not been prepared for this dam, but it has not experienced any modifications since its completion.

Water resource and climate enthusiasts interested in the infrastructure and management of dams for flood risk reduction will find Dd No 101 to be an intriguing case study. With its unique design features and state regulatory oversight, this dam showcases the importance of maintaining and monitoring critical infrastructure to mitigate potential risks and protect surrounding communities from flooding events.

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.
