Summary
This earth dam, completed in 1976, serves multiple purposes including fire protection, stock, and small fish pond maintenance, as well as flood risk reduction for the local community. With a dam height of 28 feet and a storage capacity of 86 acre-feet, this site plays a crucial role in managing water levels in the area.
Situated along the TR South Wyacondah River, this watershed site covers a drainage area of 0.14 square miles and has a surface area of 6 acres. Despite its low hazard potential and moderate risk assessment rating, the condition of the dam has not been rated yet. Managed by the Iowa DNR, this site undergoes regular state inspections, permitting, and enforcement to ensure its operational integrity and safety. The dam's uncontrolled spillway type and lack of outlet gates highlight the need for ongoing monitoring and risk management measures to protect the surrounding community and environment.
With its strategic location and vital role in water resource management, the Big Wyacondah Watershed Site 13 serves as a key asset for the local government of Wyacondah, Missouri. As climate change continues to impact water resources and ecosystems, the importance of maintaining and safeguarding such infrastructure becomes increasingly crucial. By working closely with state and federal agencies, the community can ensure the longevity and effectiveness of this watershed site for years to come.

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.
