Summary

It was completed in 1954 for the primary purpose of irrigation, with a maximum storage capacity of 6,870 acre-feet and a normal storage capacity of 5,231 acre-feet. The dam is an earth structure with a hydraulic height of 105 feet and a structural height of 115 feet, making it an essential resource for water supply in the region.

Managed by the Utah Division of Water Rights, Mill Meadow is subject to state regulations, inspections, and enforcement to ensure its safety and functionality. The reservoir covers a drainage area of 178 acres and has a spillway width of 110 feet. Despite being classified as having a high hazard potential, the dam is currently in satisfactory condition as of its last assessment in 2020. With its strategic location and significant storage capacity, Mill Meadow plays a crucial role in water resource management and climate resilience efforts in the area.

Overall, Mill Meadow stands as a vital infrastructure for water supply and irrigation in Wayne County, Utah. Its efficient design and consistent regulatory oversight ensure the safety and reliability of this essential resource for both agricultural and environmental purposes. As climate change continues to impact water availability, reservoirs like Mill Meadow are critical for ensuring sustainable water management practices and adapting to the evolving climate conditions 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.
