Summary
Its primary purpose is flood risk reduction, with a dam height of 29 feet and a length of 180 feet. The dam has a storage capacity of 158.72 acre-feet and a normal storage of 13.6 acre-feet, covering a surface area of 2.38 acres and draining a 0.46 square mile area.
Despite being classified as a low hazard potential structure with a moderate risk assessment, Dd No 12-9 (Becker) has not been rated for its condition assessment. The dam does not have any outlet gates or locks, and its spillway type is uncontrolled with a width of 60 feet. The structure has not undergone any modifications in recent years and has not been inspected or assessed for emergency preparedness, inundation mapping, or risk management measures. Its risk assessment remains at a moderate level, with no specific risk characterization or management guidelines in place.
Overall, Dd No 12-9 (Becker) plays a crucial role in mitigating flood risks in the area, serving as a vital infrastructure for the local community. However, there is a need for further assessment and evaluation of the dam's condition, emergency preparedness, and risk management measures to ensure its continued functionality and effectiveness in the face of potential climate challenges and water resource management issues.

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.
