Summary

Bright for the primary purpose of recreation. Completed in 1970, this earth dam stands at a height of 33 feet and spans a length of 333 feet, with a storage capacity of 464 acre-feet. Situated on TR-Potteroff Creek, the dam serves as a recreational water resource in Decatur County, offering a surface area of 18 acres for outdoor enthusiasts to enjoy.

Managed by the Iowa Department of Natural Resources, Slip Bluff Park Dam is regulated, inspected, and enforced for safety and compliance. With a low hazard potential and a moderate risk assessment rating, the dam remains a popular destination for locals and visitors seeking outdoor activities such as fishing, boating, and picnicking. Although the condition assessment is not rated, the structure is deemed safe for use, and no emergency action plan (EAP) is currently in place, indicating a minimal risk to the surrounding community.

The tranquil setting of Slip Bluff Park Dam, nestled in the picturesque countryside of Iowa, offers a peaceful retreat for water resource and climate enthusiasts alike.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
