Summary

Built in 1961, this earth dam serves multiple purposes including fire protection, stock maintenance, and flood risk reduction. With a height of 24 feet and a storage capacity of 102 acre-feet, this dam plays a crucial role in regulating water flow in the TR-WATERMAN CREEK.

Managed by the Iowa Department of Natural Resources, this dam has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. Despite its moderate risk level, the dam's emergency action plan status and risk management measures are currently not available. The surrounding area covers approximately 2.26 square miles and has a drainage area of 5 square miles, making it a key component in the local water supply infrastructure.

Overall, the Waterman-Spring Subwtrshd Sta 133+55 #2 is an essential structure for water management in the Cherokee area. With its strategic location and multi-purpose design, this dam plays a crucial role in ensuring water security, flood prevention, and resource conservation in the region. As climate change continues to impact water resources, the maintenance and monitoring of this dam will be vital in safeguarding the local community from potential water-related risks.

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.
