Summary
Completed in 2006, this earth dam stands at a height of 22 feet with a length of 530 feet, providing storage for 78 acre-feet of water in its reservoir. With a low hazard potential and a moderate risk assessment rating, this dam is regulated by the Iowa Department of Natural Resources and undergoes regular state inspections and enforcement measures to ensure its safety and functionality.
Situated in the Tr-East Fk Grand River, this dam serves a crucial role in managing flood risk in the area and protecting surrounding communities from potential inundation. With a spillway width of 20 feet and uncontrolled spillway type, the dam is equipped to handle excess water flow during heavy rainfall events. Despite its earth construction and stone core, the dam is considered to be in fair condition and has not been rated for its current state. While the dam has not been modified in recent years, its operational and emergency preparedness measures remain unclear, highlighting the importance of ongoing monitoring and maintenance to uphold its effectiveness in flood risk reduction efforts.
Overall, East Fork Grand River Watershed Site A-95 is a vital infrastructure component in the region's water resource and climate management strategy, overseen by local government authorities and the USDA NRCS. With its strategic location and purposeful design, this dam plays a significant role in safeguarding against potential flood hazards and ensuring the resilience of the surrounding communities in Ringgold County, Iowa. As climate change continues to pose challenges to water resource management, the maintenance and upkeep of structures like East Fork Grand River Watershed Site A-95 are essential to mitigating risks and promoting sustainable water management practices in the region.

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.
