Summary
This earth dam, completed in 1957, serves multiple purposes including fire protection, stock, and small fish pond, as well as flood risk reduction. With a dam height of 27 feet and a storage capacity of 48 acre-feet, it covers a surface area of 2.9 acres and drains a 0.13 square mile area. Despite having a low hazard potential and being in a not-rated condition assessment, it still poses a moderate risk, emphasizing the importance of ongoing monitoring and maintenance.
Located in Turin, Iowa, the dam on TR-Wolf Creek is regulated and inspected by the Iowa Department of Natural Resources, with state permitting, inspection, and enforcement in place. The dam has an uncontrolled spillway type and no outlet gates, with a historical context of no modifications or associated structures. The risk management measures for this dam are currently unspecified, highlighting the need for continued assessment and preparation for potential emergencies. Overall, Little Beaver Subwatershed 2-13001 plays a crucial role in water resource management and climate resilience efforts in the region.
As climate change impacts continue to affect water resources, the significance of structures like Little Beaver Subwatershed 2-13001 cannot be understated. With its storage capacity and flood risk reduction capabilities, this dam provides essential services to the local community while also posing manageable risks. As discussions around water resource management and climate adaptation strategies evolve, ongoing monitoring and maintenance of dams like this one will be crucial to ensure their continued effectiveness and safety for surrounding areas.

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.
