Summary

Built in 1969 by the USDA NRCS, this earth dam serves multiple purposes including fire protection, stock watering, small fish pond maintenance, and flood risk reduction. With a dam height of 33 feet and a storage capacity of 32 acre-feet, this structure plays a vital role in managing water resources in the region.

The dam, situated along the TR-East Nishnabotna River, covers a drainage area of 0.28 square miles and has a surface area of 2.5 acres. Despite a low hazard potential, the condition of the dam has not been rated and the last inspection dates back to December 1986. The risk assessment for this site indicates a moderate level of risk, emphasizing the importance of regular monitoring and maintenance to ensure the safety and effectiveness of this water resource infrastructure.

Managed by the Iowa DNR, this site is subject to state regulations, permitting, inspection, and enforcement. With Cindy Axne (D) serving as the Congress representative for the area, the Pierce Creek No 1 Watershed Site 16 stands as a testament to collaborative efforts in water resource management and climate resiliency. Enthusiasts and stakeholders in water resources and climate will find this site an intriguing example of sustainable infrastructure for both environmental protection and community well-being.

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.
