Summary
This earth dam stands at a height of 27 feet and spans 535 feet, providing grade stabilization in an area with a drainage area of 0.36 square miles. With a storage capacity of 121 acre-feet, the dam serves a vital purpose in managing water flow and preventing erosion in the region.
Managed by the Iowa DNR, Site A-60 is regulated, permitted, inspected, and enforced by state authorities to ensure its structural integrity and safety. While the dam has a low hazard potential, it is rated as moderate in terms of risk, indicating the importance of ongoing monitoring and maintenance. Despite its low hazard potential, the dam plays a crucial role in the overall water resource management of the East Fork Grand River, contributing to the sustainability and resilience of the local ecosystem.
As part of the larger water resource infrastructure in the area, Site A-60 underscores the collaborative efforts between local government entities, federal agencies, and conservation organizations to protect and enhance the natural environment. With its strategic location and purposeful design, this dam exemplifies the intersection of human ingenuity and environmental stewardship in addressing the challenges of climate change and water resource management in the East Fork Grand River Watershed.

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.
