Summary

Built in 1953 for irrigation purposes, this structure stands at 20 feet high and spans 1343 feet in length, with a storage capacity of 387 acre-feet. Despite its low hazard potential, the dam is currently in poor condition, requiring attention and maintenance to ensure its continued safety and functionality.

With a hydraulic height of 14 feet and a spillway width of 20 feet, Paul poses a moderate risk due to its poor condition assessment. While it has not been modified in recent years, the dam's inspection frequency is set at every 5 years to monitor its structural integrity. The dam is equipped with a slide sluice gate as its outlet gate, and although it has a low hazard potential, its risk assessment rating indicates the need for proactive risk management measures to mitigate any potential issues.

Located within Congressional District 00, Wyoming, Paul is under state jurisdiction and regulated by the Wyoming State Engineer's Office. The dam's emergency action plan status and risk management measures are currently unspecified, highlighting the importance of consistent monitoring and maintenance to ensure the safety of this essential water resource for irrigation in the region.

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.
