Summary

Vrain Creek. Built in 1898 for irrigation purposes, this dam stands at 21 feet high and spans 440 feet in length, with a storage capacity of 71 acre-feet. Despite its age, Moeller is in fair condition with a low hazard potential, making it a crucial component of the local water resource infrastructure.

Managed by the Colorado Division of Water Resources, Moeller undergoes regular state inspections, enforcement, and permitting to ensure its safety and functionality. The dam's spillway is uncontrolled, with a width of 8 feet, and a maximum discharge of 20 cubic feet per second. While the risk assessment for Moeller is moderate, the dam has not been modified in recent years, indicating a need for continued monitoring and potential risk management measures in the future.

Overall, Moeller serves as a vital structure for irrigation in Weld County, Colorado, supporting agricultural activities and water supply in the region. As water resource and climate enthusiasts, understanding the importance of maintaining and monitoring dams like Moeller is essential for sustainable water management practices and environmental stewardship in the face of changing climate conditions.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
