Summary
Completed in 2010, this earth dam stands at a height of 21 feet and spans 670 feet in length, with a maximum storage capacity of 90 acre-feet. The primary purpose of the dam is flood risk reduction, with additional benefits for fish and wildlife pond creation, grade stabilization, and recreation.
This site, regulating by the Iowa DNR, is situated in an area prone to low hazards, with a condition assessment currently not rated. With a drainage area of 0.27 square miles and a surface area of 6 acres, East Fork Grand River Watershed Site A-68 plays a crucial role in managing water resources and mitigating flood risks in the region. As climate change continues to impact weather patterns, structures like this are essential for protecting communities and ecosystems from the increasing threats of flooding and water scarcity.
With a primary source agency in Iowa and a location in the vicinity of Hackberry Creek, this dam serves as a vital component of the water infrastructure in the area. As water resource and climate enthusiasts, understanding the importance of structures like East Fork Grand River Watershed Site A-68 is crucial for promoting sustainable water management practices and resilience in the face of changing environmental conditions.

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.
