Summary
This Earth-type dam, completed in 1984, serves a primary purpose of "Other" and has a height of 24 feet and a length of 520 feet. With a normal storage capacity of 17 acre-feet and a drainage area of 0.42 square miles, this dam on TR-ELK CR. plays a crucial role in water resource management in the region.
Managed by the Iowa DNR and regulated at the state level, Ringgold County Roadgrade Dam 23-70-28 has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. Despite its moderate risk level, the dam has not been fully assessed for emergency action planning, although it meets regulatory guidelines. With its uncontrolled spillway type and moderate risk level, this dam is an important piece of infrastructure in the area, serving both water resource and climate conservation efforts.
As water resource and climate enthusiasts, keeping an eye on the maintenance and regulation of Ringgold County Roadgrade Dam 23-70-28 is essential for ensuring its continued effectiveness in managing water flow and storage in the region. With its moderate risk level and low hazard potential, this dam highlights the importance of proactive management and monitoring in safeguarding our water resources and adapting to changing climate conditions for a sustainable future.

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.
