Summary
No. 2 Site J-5 is a water resource structure located in Page County, Iowa, designed by the USDA NRCS and completed in 1980. This earth dam, with a height of 25 feet and a length of 520 feet, serves multiple purposes including fire protection, stock, small fish pond, and flood risk reduction. The dam has a storage capacity of 73 acre-feet and covers a surface area of 5.1 acres, with a drainage area of 0.26 square miles.
Managed by the local government, the Pierce Cr. No. 2 Site J-5 is regulated by the Iowa DNR and undergoes state permitting, inspection, and enforcement. Classified as having a low hazard potential and a moderate risk level, this structure plays a crucial role in water management and protection in the area. Despite not having a condition assessment rating, the dam continues to provide essential services to the community, demonstrating the importance of maintaining and monitoring water resource infrastructure for climate resilience and sustainability.
With its strategic location near the TR- E. Nishnabotna River and under the jurisdiction of the Iowa Department of Natural Resources, Pierce Cr. No. 2 Site J-5 exemplifies the collaborative efforts between local and state agencies in safeguarding water resources. As a multi-purpose dam serving various needs and contributing to flood risk reduction, this structure showcases the significance of effective water resource management in mitigating climate-related challenges and protecting communities from potential hazards.

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.
