Summary
Completed in 2000, this earth dam stands at a height of 18 feet and spans a length of 554 feet. With a maximum storage capacity of 62 acre-feet and a normal storage of 22 acre-feet, the dam serves as a crucial resource for water management in the area.
The dam is regulated by the Iowa DNR and undergoes regular inspections, with a low hazard potential and a moderate risk assessment rating. While the dam does not have a designated spillway, it is designed to handle controlled overflow events. The surrounding area boasts a surface area of 5.4 acres and a drainage area of 0.18 square miles, providing essential habitat for local wildlife and contributing to the overall ecological health of the region.
Despite its relatively low hazard potential, Greenlee Dam plays a vital role in water resource management and climate resilience efforts in Wayne County, Iowa. As enthusiasts of water resources and climate initiatives, understanding the infrastructure and regulatory framework of dams like Greenlee is crucial in ensuring the sustainable use of water resources and the protection of ecosystems in the face of a changing climate.

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.
