Summary
This earth-type dam, standing at 34 feet tall and stretching 1805 feet in length, was completed in 1964 and has since been regulated by the Colorado Department of Water Resources. With a storage capacity of 2144 acre-feet and a drainage area of 8 square miles, the dam plays a vital role in mitigating potential hazards and maintaining the safety of the surrounding communities.
Despite its fair condition assessment as of November 2018, Limon Watershed L-1 is classified as having a high hazard potential, underscoring the importance of regular inspections and maintenance. The dam's emergency action plan (EAP) status and risk assessment further highlight the need for ongoing risk management measures to ensure the safety and security of residents in the event of a potential breach or emergency situation. With a moderate risk rating and regular inspection frequency, stakeholders and local authorities must remain vigilant in monitoring and addressing any potential vulnerabilities to uphold the dam's integrity and safeguard the community's well-being.

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.
