Summary

Completed in 1999, this earth dam with a height of 39.3 feet and a length of 657 feet has a storage capacity of 196 acre-feet, providing essential water storage for the surrounding area. The dam, constructed on TR Cow Creek, plays a crucial role in managing water supply and mitigating flood risks in the region.

With a spillway width of 23 feet and uncontrolled spillway type, the dam is designed to handle a maximum discharge of 66 cubic feet per second. The structure is inspected regularly to ensure its safety and effectiveness in water management. Despite being privately owned, the dam is subject to state permitting and inspection, highlighting the importance of regulatory oversight in maintaining the integrity of water infrastructure.

Overall, Whitewater Springs Dam represents a significant investment in water resource management in Texas. With its moderate risk assessment and essential role in water storage and flood control, this dam plays a crucial part in ensuring the sustainability and resilience of the region's water supply in the face of changing climate conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
