Summary

This earth dam, completed in 1966, stands at a hydraulic height of 110 feet and a structural height of 118 feet, with a total length of 960 feet. It has a storage capacity of 1432 acre-feet and serves Settlement Creek, with a drainage area of 17 square miles.

Despite being regulated by the Utah Division of Water Rights and subject to state inspection, Settlement Canyon poses a high hazard potential due to its location and design. The dam is rated in fair condition, with an inspection frequency of once a year. The last inspection was conducted in September 2020, and it meets the state's regulatory requirements for permitting, inspection, and enforcement.

Water resource and climate enthusiasts will find Settlement Canyon an intriguing case study of a privately owned irrigation dam in a semi-arid region. With its high hazard potential and fair condition assessment, the dam serves as a reminder of the importance of proper maintenance and monitoring of critical water infrastructure in the face of changing climate conditions and increasing water demands.

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.
