Summary
The dam, completed in 1983, serves the primary purpose of irrigation, drawing water from Muddy Creek for agricultural use. With a hydraulic height of 13 feet and a structural height of 14 feet, the dam has a storage capacity of 9 acre-feet and a drainage area of 0.2 square miles.
Located in Emery County, Utah, this earth dam poses a significant hazard potential and undergoes inspections every two years, with the last assessment conducted in May 2004. The condition assessment is currently not rated, highlighting the need for further evaluation and potential maintenance. While the dam's emergency action plan status and risk management measures are not specified, its critical role in providing water resources for irrigation underscores the importance of ensuring its safety and proper functioning in the face of climate change challenges.
As water resource and climate enthusiasts, monitoring and maintaining the Castle Valley Special Service District in Emery Town Upper is essential for safeguarding local water supplies in the region. With its close association with Muddy Creek and its critical role in supporting agricultural activities, this irrigation infrastructure serves as a vital lifeline for the community. By staying informed about its condition, potential risks, and regulatory oversight, stakeholders can actively contribute to the resilience of this dam and ensure sustainable water management practices for the future.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
