Summary
Completed in 2007, this earth dam stands at 17 feet high and spans 555 feet in length, serving primarily for recreational purposes. With a storage capacity of 104 acre-feet and a surface area of 8.8 acres, this dam is situated on the Tr- West Branch Floyd River, under the regulatory oversight of the Iowa Department of Natural Resources.
Despite its satisfactory condition assessment as of May 2019, the South Ridge Estates - East Dam poses a high hazard potential, prompting biennial inspections to ensure its structural integrity and safety. With a moderate risk assessment rating, this dam plays a crucial role in flood control and water resource management in the region. As a key component of the local landscape, its maintenance and regulatory compliance are essential for the protection of surrounding communities and the environment.
As climate change continues to impact water resources and weather patterns, the South Ridge Estates - East Dam stands as a vital infrastructure for mitigating flood risks and providing recreational opportunities.

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.
