Summary
This earth dam stands at 23 feet tall and spans 455 feet, with a storage capacity of 55 acre-feet. The dam is situated on TR- WOLF CREEK, with a drainage area of 0.17 square miles and a surface area of 3.1 acres.
Managed by the Iowa DNR, this site is regulated by the state and undergoes regular inspections, enforcement, and permitting. Despite its low hazard potential and moderate risk assessment, the condition of the dam is currently unrated. The primary purpose of West Fk Big Cr Watershed Site W-2 is flood risk reduction, serving as a critical infrastructure for protecting the surrounding area from potential flooding events.
With its location in a state-regulated watershed and its importance in mitigating flood risks, West Fk Big Cr Watershed Site W-2 serves as a vital component in the water resource management efforts in the region. Enthusiasts interested in water resource and climate conservation will find this structure to be a fascinating example of sustainable infrastructure design and management in the face of changing environmental conditions.

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.
