Summary
This site, situated along the TR-South Wyacondah River, serves multiple purposes including fire protection, stock, or small fish pond maintenance, and flood risk reduction. The primary dam type at this site is earth, with a height of 16 feet and a length of 512 feet, providing a storage capacity of 160 acre-feet. The watershed covers a drainage area of 0.6 square miles with a surface area of 10 acres.
Constructed in 1966, Big Wyacondah Watershed Site 32-1 is regulated by the Iowa Department of Natural Resources (DNR) and is subject to state permitting, inspection, and enforcement. Despite having a low hazard potential, the site has a moderate risk assessment rating of 3, suggesting a need for ongoing risk management measures. The emergency action plan (EAP) status, condition assessment, and inundation maps for the area are currently not rated or prepared, highlighting areas for potential improvement in emergency preparedness and response.
Overall, Big Wyacondah Watershed Site 32-1 is a significant water resource in the region, contributing to fire protection, agricultural activities, and flood risk mitigation. With its strategic location and design, this site plays a vital role in water management and conservation efforts, emphasizing the importance of ongoing monitoring, maintenance, and emergency preparedness to ensure the safety and sustainability of the surrounding environment and communities.

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.
