Summary
Completed in 2005, this earth dam stands 25 feet tall and extends 563 feet in length, with a storage capacity of 86 acre-feet. With a low hazard potential and a moderate risk assessment rating, this structure plays a crucial role in safeguarding the surrounding area from potential flooding events.
Managed by the Iowa Department of Natural Resources, this dam is regulated, permitted, inspected, and enforced to ensure its structural integrity and functionality. The site is situated in Ringgold County, Iowa, and its location at NW,SE,S6,T069N,R28W makes it a strategic point for managing the flow of the TR- East Fork Grand River. Despite not being rated for condition assessment, this dam is maintained to meet guidelines and protect the community from potential risks associated with flooding.
With a primary focus on flood risk reduction, Site A-96 serves as a testament to effective water resource management and climate adaptation strategies in the region. Operated by local government authorities with support from the NRCS, this structure exemplifies the collaborative efforts required to address environmental challenges and protect communities from the impacts of extreme weather events. As a key component of the watershed's infrastructure, this dam plays a crucial role in mitigating flood risks and ensuring the safety and well-being of the surrounding area.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
