Summary
With a height of 19 feet and a length of 485 feet, the dam has a storage capacity of 58 acre-feet and a surface area of 5 acres. It is regulated by the Iowa Department of Natural Resources and is inspected and enforced by state authorities, ensuring its safety and compliance with regulations.
The dam poses a significant hazard potential and has a moderate risk rating, indicating the need for proper risk management measures. While the condition assessment is not rated, the dam has not been modified in recent years. It is situated on the TR-Mississippi River and falls under the jurisdiction of the Rock Island District of the US Army Corps of Engineers. Despite being privately owned, the dam plays a crucial role in water resource management and protection in the area.
Water resource and climate enthusiasts will find Hon Dam an interesting structure to study due to its unique design, purpose, and location on the Mississippi River. With a focus on fire protection and stock activities, the dam serves both practical and environmental functions in the region. As a regulated and inspected facility, it highlights the importance of maintaining and managing water infrastructure to ensure safety and sustainability for surrounding communities and ecosystems.

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.
