Summary
Located in Davis, Iowa, this earth dam structure was completed in 1964 and has a dam height of 25 feet, a length of 585 feet, and a storage capacity of 99 acre-feet. Managed by the USDA NRCS, this site is regulated by the Iowa Department of Natural Resources and undergoes regular inspections and enforcement to ensure its functionality and safety.
Situated along the TR-South Wyacondah River, this watershed site plays a crucial role in flood risk reduction and water management for the surrounding area. With a drainage area of 0.28 square miles and a surface area of 6 acres, it is designed to control water flow and protect against potential hazards. Despite its low hazard potential and moderate risk assessment rating, the condition assessment of this site is currently not rated, highlighting the need for continued monitoring and maintenance to uphold its effectiveness in water resource management and climate adaptation efforts.
As climate change continues to impact water resources, the significance of sites like Big Wyacondah Watershed Site 42 becomes increasingly apparent. With its strategic location and purposeful design, this watershed site serves as a critical infrastructure for water supply, flood control, and environmental resilience in the region. By staying updated on its maintenance, regulation, and risk management measures, stakeholders can ensure the long-term sustainability and effectiveness of this essential water resource facility.

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.
