Summary
This privately owned earth dam stands at a height of 16 feet and spans a length of 1650 feet, with a storage capacity of 166 acre-feet. Situated on the TR-San Ambrosia Creek, it plays a vital role in water resource management in the region.
Despite being unregulated by the state and having no official hazard potential assessment, the dam poses a high risk due to its age and unknown condition assessment. With no spillway and limited discharge capacity, the dam may face challenges during extreme weather events, emphasizing the importance of regular inspection and maintenance. The presence of only one outlet gate further raises concerns about the dam's ability to manage water levels effectively.
For water resource and climate enthusiasts, Cage Lake No 1 Dam presents an intriguing case study in the intersection of infrastructure, water management, and climate resilience. Its location on a creek in a region vulnerable to drought and flooding underscores the importance of monitoring and maintaining aging dams for both human safety and ecological health. As a privately owned structure with limited state oversight, the dam serves as a reminder of the diverse challenges facing water resource management in the face of a changing climate.

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.
