Summary

Managed by the Bureau of Reclamation, this earth dam structure stands at a height of 218 feet and has a hydraulic height of 187 feet, providing essential water storage for irrigation purposes since its completion in 1966. With a maximum storage capacity of 8730 acre-feet and a normal storage capacity of 7870 acre-feet, Causey Reservoir plays a crucial role in water resource management in the region.

Situated on the South Fork of the Ogden River, this reservoir covers a surface area of 136 acres and has a drainage area of 81 square miles. The dam is designed with an uncontrolled spillway and has a high hazard potential, making it vital for regular inspections and risk assessments. While the condition assessment is currently not available, Causey Reservoir is marked as a moderate risk (3) based on the risk assessment conducted. With its strategic location and significant contribution to irrigation needs, Causey is a key component of the water infrastructure in Utah.

Despite its importance, Causey Reservoir does not fall under state jurisdiction for regulation, permitting, or inspection. Managed solely by the Bureau of Reclamation, the reservoir's operations, regulatory affairs, and inspections are overseen by the federal agency. With Congressman Rob Bishop representing the area, Causey continues to serve as a critical resource for water supply and irrigation in the region, highlighting the intricate relationship between water resources, climate conditions, and federal management practices.

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.
