Summary
This earth dam was completed in 1965 and serves multiple purposes including fire protection, stock watering, and small fish pond management. With a dam height of 27 feet and a normal storage capacity of 28 acre-feet, this structure helps to reduce flood risks in the area while also providing essential water resources for local needs.
Managed by the USDA NRCS and regulated by the Iowa DNR, Arlington Subwtrshd Sta 62+50 #3 has a low hazard potential and a moderate risk assessment rating. The dam is situated on the TR-W Fork Little Sioux River and has a drainage area of 0.49 square miles, with a surface area of 2.7 acres. Despite being not rated for its current condition assessment, this structure plays a crucial role in water management and conservation efforts in the region.
With an uncontrolled spillway type and a maximum storage capacity of 65 acre-feet, Arlington Subwtrshd Sta 62+50 #3 is an important asset for water resource and climate enthusiasts. Its strategic location and multiple functionalities make it a valuable component of the local water infrastructure, ensuring water supply reliability and flood protection for the community.

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.
