Summary
This private-owned Earth dam serves the primary purpose of water supply, with a storage capacity of 83 acre-feet and a normal storage of 56 acre-feet. The dam, located on TR-Santa Isabel Creek, plays a crucial role in managing water resources in the region, ensuring a steady supply for local communities.
Despite being unregulated by the state, Chupahueso Lake No 1 Dam has been designed for safety with a buttress core type and a hazard potential currently labeled as 'Not Available.' The risk assessment indicates a high risk level, emphasizing the importance of regular inspections and maintenance to ensure the dam's stability and functionality. While lacking certain regulatory oversight, the dam's role in water management and supply underscores its significance in the region's water resource infrastructure.
As an essential component of the local water supply system, Chupahueso Lake No 1 Dam plays a critical role in meeting the water needs of the surrounding area. With its construction completed over five decades ago, the dam's structure and capacity continue to support the community's water requirements, highlighting the ongoing importance of maintaining and monitoring this key water resource infrastructure.

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.
