Summary
Built in 1960 by the USDA NRCS, this earth dam stands at a height of 34 feet and spans 542 feet in length, providing a storage capacity of 36 acre-feet. With a low hazard potential and a moderate risk assessment rating, this dam serves as a vital resource for water management in the area.
Managed by the Iowa DNR, this dam on TR-Camp Creek has a surface area of 2.3 acres and drains an area of 0.4 square miles. While it has not been inspected since 1989, it is designed with an uncontrolled spillway and soil foundation. The dam poses a low risk to surrounding areas but falls under state jurisdiction for inspection, permitting, and enforcement. As water resource and climate enthusiasts, monitoring and maintaining infrastructure like Heisler Creek Subwatershed Station 46+80 #3d is crucial for sustainable water management and protection against potential hazards.
In the event of emergencies, it is essential that an Emergency Action Plan (EAP) is in place, although details about the preparation and last revision of the EAP for this dam are currently unavailable. With a congressman, Steve King (R), representing the area, and the Omaha District of the USACE overseeing the dam, stakeholders must prioritize regular inspections, risk assessments, and appropriate risk management measures to ensure the safety and reliability of this critical water resource for the community.

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.
