Summary
Managed by the local government and designed by the USDA NRCS, this earth dam stands at a height of 21 feet and stretches 580 feet in length. Completed in 2006, the dam has a storage capacity of 114 acre-feet and serves the primary purpose of flood risk reduction for the Tr-Hackberry Creek.
With a low hazard potential and a moderate risk assessment rating, East Fork Grand River Watershed Site A-67 plays a crucial role in managing water resources in the region. Although the dam is not currently rated for its condition, it is regularly inspected, permitted, and regulated by the Iowa DNR. The spillway type is uncontrolled with a width of 20 feet, ensuring that excess water can be safely discharged during heavy rainfall events. The structure's location, design, and construction all contribute to its effectiveness in mitigating flood risks and protecting the surrounding area.
As water resource and climate enthusiasts, the data for East Fork Grand River Watershed Site A-67 provides valuable insights into the management of water infrastructure in the region. With a focus on flood risk reduction and a solid foundation of soil and stone, this dam exemplifies the importance of proactive measures in safeguarding communities from the impacts of extreme weather events. As efforts continue to monitor and maintain the structure, it remains a vital component in the overall resilience of the watershed and the sustainability of water resources in the 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.
