Summary

Built in 1985 by designers Speaker & King, this dam serves the primary purpose of flood risk reduction with a storage capacity of 113 acre-feet and a normal storage of 22 acre-feet. With a dam height of 23 feet and a length of 790 feet, the structure boasts a surface area of 4.9 acres and drains a 0.27 square mile area.

Managed by the local government, Gs Dd No A-71 has not been rated for condition assessment and falls under the moderate risk category. Although it has an uncontrolled spillway type with a width of 31 feet, the dam has not had any associated structures or inspections in recent years. Despite its low hazard potential, the risk assessment for Gs Dd No A-71 remains at a moderate level, highlighting the importance of ongoing monitoring and management measures.

Located within the Kansas City District, this dam serves as a vital infrastructure for flood risk reduction in the region. With its strategic placement along the Straight Creek-TR river, Gs Dd No A-71 plays a crucial role in protecting the surrounding areas from potential inundation events. For water resource and climate enthusiasts, this dam offers a fascinating glimpse into the intersection of infrastructure, environmental management, and public safety in the face of changing climate patterns.

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.
