Summary
This earth dam stands at a height of 26 feet with a length of 290 feet, providing a storage capacity of 55 acre-feet. Situated on TR-Shoal Creek, the dam serves as a crucial infrastructure for water resource management in the area, with a low hazard potential and a moderate risk assessment.
Managed by the Iowa DNR, this dam is state-regulated, permitted, inspected, and enforced to ensure its structural integrity and safety. Despite being uncontrolled, the spillway type and other design features contribute to its operational efficiency. With a drainage area of 0.48 square miles and a surface area of 5 acres, Appanoose County Roadgrade Dam 27-68-19 plays a vital role in maintaining water levels and supporting various ecosystem functions in the region. As a key component of the local water infrastructure, this dam exemplifies the importance of sustainable water resource management practices in mitigating climate-related risks and enhancing community resilience.

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.
