Summary
Built in 1940, this earth dam stands at a height of 14 feet and spans a length of 2200 feet, with a storage capacity of 308 acre-feet. It is primarily designed for water supply purposes, reflecting its importance in sustaining local water resources for agricultural and livestock needs.
Despite its age, Griffin Cattle CO Lake Dam has not been rated for its condition assessment, with a high risk potential identified. While it lacks a spillway and has limited information on its foundations, the dam remains a critical infrastructure for water management in the area. With state permitting and inspection in place, efforts are being made to ensure the dam's safety and functionality for the surrounding community.
As climate change impacts water resources, structures like Griffin Cattle CO Lake Dam play a crucial role in ensuring water availability and security. With ongoing risk management measures needed and potential for improvements in safety features, this dam represents a key site for water resource and climate enthusiasts to monitor and support in safeguarding the region's water supply.

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.
