Summary

This Earth-type dam stands at 23 feet tall and has a hydraulic height of 16.4 feet, providing a storage capacity of 19.76 acre-feet. Despite not having a designated purpose, the dam serves a vital role in the region's water management, with a drainage area of 0.8 square miles and a maximum discharge of 24.53 cubic feet per second.

Located in Sevier County, Utah, Monroe City's dam has a significant hazard potential, although its condition assessment remains unrated. With a last inspection date unknown, the dam is subject to biennial inspections to ensure its operational integrity. While the Emergency Action Plan status and risk management measures are not specified, the dam's critical role in water resource management underscores the need for continued regulatory oversight and maintenance to mitigate potential risks to the surrounding community and environment.

Chris Stewart, the Republican Representative for Utah's Congressional District, oversees Monroe City's dam within the Los Angeles District of the US Army Corps of Engineers. With its strategic location and essential water storage capacity, Monroe City's dam serves as a crucial infrastructure for water resource management in the region, highlighting the importance of ongoing monitoring and maintenance to ensure its long-term effectiveness and safety.

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.
