Summary
The dam, with a height of 7 feet and a storage capacity of 613 acre-feet, serves primarily for recreational purposes along the TR- Iowa River. It is regulated by the Iowa Department of Natural Resources and is inspected and enforced by state authorities to ensure its safety and compliance with regulatory standards.
With a low hazard potential and a moderate risk assessment, Hawk Investments Dam is considered a safe structure within the Detroit District. Despite being classified as "Not Rated" in terms of condition assessment, the dam's purpose of recreation and its minimal impact on the surrounding environment make it a key feature in the local water resource management system. The dam, with its earth construction and soil foundation, has a surface area of 89.7 acres and a drainage area of 0.78 square miles, providing a valuable recreational space for the community and visitors alike.
Overall, Hawk Investments Dam stands as a testament to the importance of water resource management and climate resilience in enhancing recreational opportunities while ensuring the safety and well-being of the local environment. As water resource and climate enthusiasts, it is crucial to recognize the role of dams like Hawk Investments in balancing human needs with ecological sustainability, providing a model for responsible water infrastructure development in the face of changing climate conditions.

Dam Data Reference
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.
