Summary
Constructed in 1966 by the USDA NRCS, this earth dam stands at a height of 36 feet and stretches 594 feet in length. With a storage capacity of 186 acre-feet, the dam covers a surface area of 10.9 acres and serves a drainage area of 0.85 square miles.
Owned and regulated by the local government and the Iowa Department of Natural Resources, the Moorhead Pioneer Park Dam boasts a low hazard potential and is classified as having a moderate risk level. The dam features an uncontrolled spillway and is primarily made of soil materials for its foundations. While it has not been rated for its condition assessment, the dam remains under state inspection, permitting, and enforcement to ensure its structural integrity and safety for the surrounding community.
As a vital asset for water resource management and climate resilience in the region, the Moorhead Pioneer Park Dam plays a critical role in providing essential services such as water storage, flood control, and recreational opportunities. With its historical significance and ongoing regulatory oversight, the dam continues to be a key component in safeguarding the local environment and enhancing the quality of life for residents in Ida Grove, Iowa.

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.
