Summary

Designed by USDA NRCS and completed in 1961, this earth dam stands at a height of 45 feet and has a storage capacity of 182 acre-feet. Its primary purpose is irrigation, but it also serves recreational and water supply needs in the area.

The dam, situated on Dry Creek-TR, spans 607 feet in length and has a spillway width of 123 feet. With a low hazard potential and satisfactory condition assessment, Loukonen Brothers is regulated by the Colorado Division of Water Resources and undergoes regular inspections. The structure's risk assessment is moderate, indicating a need for ongoing risk management measures to ensure its continued safety and functionality.

Despite its relatively low hazard potential, Loukonen Brothers plays a crucial role in supporting agricultural activities and water resources in the region. As a key component of the local water infrastructure, this earth dam represents a blend of practical engineering and environmental stewardship, highlighting the importance of sustainable water management practices in the face of a changing climate.

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.
