Summary

Built in 1963 by the USDA NRCS, this earth dam serves the primary purpose of flood risk reduction along the Biglow Canyon river or stream. With a hydraulic height of 24 feet and a structural height of 33 feet, this dam stands at 1665 feet in length and has a normal storage capacity of 65 acre-feet.

Managed by the Utah Division of Water Rights, Juab County - Bigelow Debris is a significant structure with a hazard potential classified as "Significant." While its condition assessment is currently "Not Rated," regular inspections are conducted every two years to ensure its integrity and functionality. Despite not having a designated Emergency Action Plan (EAP) or inundation maps prepared, this dam plays a crucial role in mitigating flood risks and protecting the surrounding area from potential disasters. For water resource and climate enthusiasts, this structure stands as a vital part of the region's water management efforts and serves as a testament to the importance of proactive infrastructure development in the face of changing environmental 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.
