Summary
This earth dam, designed by USDA NRCS, stands at a height of 26 feet and spans a length of 790 feet, with a storage capacity of 121 acre-feet. The primary purpose of the dam is for fire protection, stock, or small fish pond management. It is regulated by the Iowa DNR and is subject to state permitting, inspection, and enforcement.
Situated on TR-7266 Creek, Riedmann Dam serves as a crucial water resource for the surrounding area, with a normal storage capacity of 45 acre-feet and a surface area of 7.4 acres. Despite its low hazard potential and moderate risk assessment rating, the dam's condition is currently not rated. In terms of emergency preparedness, details such as the existence of an emergency action plan and inundation maps are not specified in the available data. The dam is not under the jurisdiction of the US Army Corps of Engineers.
Overall, Riedmann Dam plays a vital role in providing water management solutions for fire protection and livestock needs in O'Brien County, Iowa. With its earth structure and state-regulated status, the dam contributes to the local ecosystem while maintaining a low hazard potential. As water resource and climate enthusiasts, understanding the importance of dams like Riedmann Dam in ensuring water security and environmental sustainability is key to promoting responsible water management practices 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.
