Summary
The primary purpose of this dam is to mitigate flood risks in the area, with a hydraulic height of 29 feet and a structural height of 33 feet. The dam has a length of 1325 feet and a storage capacity of 868 acre-feet, providing essential protection to the surrounding community in Alex.
Despite its low hazard potential, SCS-Winter Creek Site-09 is considered to have a very high risk level, emphasizing the importance of regular inspections and maintenance. The dam features a controlled spillway and one outlet valve for water release, ensuring proper water management during high flow events. While the condition assessment is currently not rated, the dam has not been inspected since 1980, highlighting the need for updated safety measures and emergency preparedness protocols.
With the potential for increased climate variability and extreme weather events in the region, the SCS-Winter Creek Site-09 serves as a crucial infrastructure for flood control and water resource management. As a vital component of the state's regulatory framework, this dam underscores the importance of proactive risk management and regular maintenance to ensure the safety and protection of the local community and surrounding environment.

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.
