Summary
The dam stands at a height of 35 feet and spans 577 feet in length, with a storage capacity of 110 acre-feet and a surface area of 7.5 acres. Situated on TR-Clear Creek, the dam is regulated by the Iowa Department of Natural Resources and is subject to state permitting, inspection, and enforcement to ensure its safety and compliance with regulations.
Despite being categorized as having a low hazard potential, Deutsch Dam is considered to have a moderate risk level, with a risk assessment rating of 3 out of 5. The dam has not been assessed for its condition and does not have an established Emergency Action Plan (EAP) in place. While the dam's maintenance and safety measures are not explicitly outlined in the available data, its location and purpose suggest its importance in providing water resources for fire protection and agricultural activities in the surrounding area. With its proximity to Mingo and the Rock Island District, Deutsch Dam serves as a vital infrastructure for water management and conservation 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.
