Summary

Completed in 1990, this earth dam stands at 24 feet high with a hydraulic height of 30 feet and a structural height of 28 feet. Boomerang serves primarily for irrigation purposes, with additional recreational benefits for the local community. The dam has a low hazard potential and is currently assessed to be in fair condition.

Managed by the Colorado Department of Water Resources, Boomerang undergoes regular state inspections, enforcement, and permitting to ensure its safety and compliance with regulations. The dam has a maximum storage capacity of 28 acre-feet and a normal storage of 16 acre-feet, covering a surface area of 2 acres. Although it has an uncontrolled spillway type, the risk assessment for Boomerang is rated as moderate (3), prompting the need for ongoing risk management measures to mitigate any potential hazards.

For water resource and climate enthusiasts, Boomerang provides a fascinating case study of a vital infrastructure supporting agricultural activities in Colorado. With its location along the Poudre River and proximity to Greeley, this dam plays a crucial role in managing water resources for irrigation while offering recreational opportunities for the local community. As efforts continue to maintain and monitor Boomerang's condition, stakeholders are reminded of the importance of sustainable water management practices to safeguard both the environment and public safety 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.
