Summary
This earth dam, completed in 1970, stands at a height of 30 feet and has a storage capacity of 151 acre-feet. With a drainage area of 390.4 square miles, the dam plays a significant role in mitigating potential flood hazards in the region.
The dam's spillway, with a width of 150 feet, helps regulate water flow during periods of high discharge, ensuring the safety of nearby communities. Despite being assessed as having a high hazard potential, the dam's condition remains unrated. Emergency action plans and risk management measures for Southwest City Rc&D Structure E-1 are yet to be fully developed, indicating a need for continued monitoring and maintenance to enhance its resilience in the face of changing climate conditions.
For water resource and climate enthusiasts, Southwest City Rc&D Structure E-1 offers a fascinating case study in flood risk reduction infrastructure. Its strategic location, design features, and operational history provide valuable insights into the challenges and opportunities associated with managing water resources in vulnerable areas. As climate change accelerates the frequency and intensity of extreme weather events, the importance of maintaining and enhancing structures like Southwest City Rc&D Structure E-1 only grows, highlighting the critical role such infrastructure plays in building resilient communities.

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.
