Summary
Built in 1965, this earth dam serves multiple purposes including fire protection, stock, and small fish pond management. With a height of 34 feet and a length of 350 feet, the dam has a storage capacity of 43 acre-feet and covers a surface area of 4.6 acres, drawing from a drainage area of 1.3 square miles.
Managed by the Monona County Engineer and USDA NRCS, the dam is designed to withstand low hazard potential, with a moderate risk assessment rating. The dam has not been rated for its current condition, but it is subject to state inspections and enforcement to ensure its safety and functionality. While the dam has no outlet gates, locks, or spillway width, it is crucial for water resource management and ecological balance in the area, particularly along the TR-Soldier River.
Water resource and climate enthusiasts will appreciate the significance of Monona County Roadgrade Dam 13-83-43 in maintaining water levels for fire protection, livestock, and fish habitats. As a key structure in the region, its construction, design, and purpose showcase the efforts to manage water resources effectively while considering environmental impacts. With its location in Monona County, Iowa, this dam stands as a testament to the importance of sustainable water management practices in maintaining a healthy ecosystem for all.

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.
