Summary

Built in 1988 by designers Speaker and King, this dam serves the primary purpose of flood risk reduction and debris control. With a height of 26 feet and a length of 720 feet, the dam has a storage capacity of 179 acre-feet and a surface area of 5.3 acres, providing vital protection to the surrounding area in Nemaha County.

Despite its low hazard potential and moderate risk assessment, Gs Dd No 29-15 has not been rated for its condition assessment. The dam features an uncontrolled spillway with a width of 79 feet and has no outlet gates. In the event of an emergency, the dam's Emergency Action Plan (EAP) status is unknown, raising concerns about the readiness of response measures. With the last inspection conducted in 2015 and no scheduled inspection frequency listed, there is a need for increased oversight and maintenance to ensure the dam's continued effectiveness in managing flood risks in the region.

Overall, Gs Dd No 29-15 plays a crucial role in protecting the local community from potential flooding events. As a key infrastructure asset in Nemaha County, it is essential for state and local agencies to prioritize the dam's maintenance and monitoring to mitigate risks and ensure the safety of surrounding residents. Additionally, updating the dam's emergency response plan and conducting regular inspections will be critical steps in enhancing the resilience of this vital water resource infrastructure.

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.
