Summary
This earth dam with a height of 12 feet and a length of 720 feet creates a reservoir with a storage capacity of 144 acre-feet. Situated on the TR-California Creek, this dam is owned privately and is not regulated by the state. Despite being classified as having a high risk potential, its condition assessment remains unrated.
With no spillway and a hazard potential that is not available, this dam is equipped with one outlet gate and has not been inspected since September 1979. The risk management measures, emergency action plan, and inundation maps for this structure are not available, raising concerns for its safety and preparedness in case of emergencies. Despite these challenges, the Three Rivers Gypsum Lake Dam continues to provide recreational opportunities for visitors in the area.
For water resource and climate enthusiasts, the Three Rivers Gypsum Lake Dam presents an intriguing case study in dam safety and management. With its location in a high-risk area and limited regulatory oversight, there is a need for improved monitoring and emergency preparedness measures to ensure the safety of the surrounding community and the dam itself. As discussions around climate change and water resource management continue, this dam serves as a reminder of the importance of proactive maintenance and risk assessment for critical infrastructure.

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.
