Summary
This dam has a height of 28 feet and a storage capacity of 90 acre-feet, serving as a vital resource for water management in the area. While the dam is state-regulated and inspected, its hazard potential is rated as low, providing a sense of security for nearby residents and wildlife.
With a maximum discharge of 350 cubic feet per second, Cable Stockwater Dam No.2 plays a crucial role in managing water flow and preventing potential flooding in the region. The dam's primary purpose is to provide stockwater for agricultural operations, highlighting its importance in sustaining local ecosystems and supporting the livelihoods of farmers and ranchers. Despite its age, the dam's condition is currently rated as 'Not Rated,' indicating a need for further assessment to ensure its long-term functionality in the face of changing climate conditions.
As climate change continues to impact water resources, the presence of well-maintained dams like Cable Stockwater Dam No.2 becomes increasingly significant in mitigating the effects of droughts and extreme weather events. By actively monitoring and managing these structures, stakeholders can work towards sustainable water management practices that benefit both the environment and the local communities. Cable Stockwater Dam No.2 stands as a testament to the importance of water resource infrastructure in adapting to a changing climate and ensuring water security for future generations.

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.
