Summary
This dam, completed in 1954, serves multiple purposes including fire protection, stock storage, and flood risk reduction. With a height of 32 feet and a length of 400 feet, it has a storage capacity of 182 acre-feet and covers a surface area of 7.9 acres. The dam is primarily constructed of earth and is regulated by the Iowa Department of Natural Resources, with regular inspections and enforcement to ensure its integrity.
The Fee Subwatershed Sta 05+00 Main Gully dam plays a crucial role in managing water resources in the area, particularly for fire protection and livestock management. Its low hazard potential and moderate risk assessment make it a reliable structure for the community. The dam, situated along the TR-Little Sioux River, has a drainage area of 0.87 square miles and is equipped with an uncontrolled spillway. Despite not being rated for condition assessment, the dam continues to serve its intended purposes effectively, with no reported incidents of overflowing or discharge issues.
Water resource and climate enthusiasts will appreciate the strategic location and design of the Fee Subwatershed Sta 05+00 Main Gully dam. Its contribution to flood risk reduction and water storage for agricultural use highlights the importance of sustainable infrastructure in addressing environmental challenges. As a regulated structure with state permitting and inspection requirements, this dam sets a standard for 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.
