Summary
Managed by the local government and designed by the USDA NRCS, this dam serves multiple purposes including fire protection, stock maintenance, and small fish pond creation. Completed in 1956, the dam has a height of 29 feet and a storage capacity of 220 acre-feet, making it an essential component for flood risk reduction in the region.
Situated along the TR-Little Sioux River, the Clark Subwatershd Sta22+82 Main Gully dam has a low hazard potential and is currently in a not-rated condition. Despite its age, the dam continues to play a crucial role in water management and conservation efforts in the area. With a moderate risk assessment of 3, it is important for the Iowa DNR to conduct regular inspections, enforce regulations, and ensure the structural integrity of the dam to prevent any potential hazards or risks to the surrounding community.
Overall, the Clark Subwatershd Sta22+82 Main Gully serves as a key infrastructure for water resource management in Cherokee, Iowa. With its multiple purposes and moderate risk assessment, it is essential for local authorities to prioritize the maintenance and monitoring of this dam to safeguard the community from potential threats and ensure the sustainable use of water resources 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.
