Summary
With a dam height of 33 feet and a length of 650 feet, this earth dam serves the primary purpose of flood risk reduction for the local community of Rodney. The dam has a storage capacity of 109 acre-feet and covers a surface area of 2.9 acres, providing protection for a drainage area of 4.01 square miles along the TR- Little Sioux River.
Managed by the Iowa DNR, the Habinck Subwatershed Sta 93+30 has a low hazard potential and a moderate risk assessment rating of 3. While the condition of the dam is currently not rated, it undergoes state inspection, enforcement, and permitting to ensure its structural integrity and functionality. The structure's emergency action plan status and risk management measures are not available, but it meets guidelines for safe operation and maintenance.
Overall, the Habinck Subwatershed Sta 93+30 plays a crucial role in protecting the Rodney community from potential flooding events. With its strategic location and design, this earth dam serves as a vital infrastructure asset for flood risk reduction along the TR- Little Sioux River, showcasing the importance of water resource management and climate resilience in the region.

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.
