Summary
This earth dam has a height of 39 feet and a length of 580 feet, providing storage of 68 acre-feet of water for the surrounding area. The dam is regulated by the Iowa DNR and undergoes regular inspections to ensure its satisfactory condition and low hazard potential.
The watershed site plays a crucial role in managing the flow of Davids Creek, a tributary of the river, and helps mitigate the risk of flooding in the region. With a drainage area of 0.18 square miles, the dam provides flood protection for the city of Exira and its residents. Despite its moderate risk assessment, the structure has been deemed to meet guidelines and is equipped with emergency preparedness measures to ensure the safety of the community in case of a potential hazard event.
Overall, Davids Creek Watershed Site 1a-3 serves as a vital infrastructure for flood control in the area, showcasing a collaborative effort between local government agencies and the USDA NRCS. With its satisfactory condition and low hazard potential, the dam stands as a testament to effective water resource management and climate resilience strategies in Iowa. Its presence not only safeguards the community from potential flooding but also underscores the importance of proactive measures in protecting our environment and communities from natural disasters.

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.
