Reynolds Dam, located in Dallam, Texas, is a privately owned structure designed by Malcalm F Miller and completed in 1956 for the primary purpose of irrigation along the Smokey Bonner Creek.


Summary

This Earth dam stands at a height of 13 feet with a length of 750 feet, providing a storage capacity of 100 acre-feet, with a normal storage level of 73 acre-feet. Despite its age, the dam has not undergone recent inspections and is labeled as having a high risk potential.

Although the dam does not have a spillway, it is equipped with one outlet gate. The structure is not currently regulated by the state and lacks a condition assessment rating, raising concerns about its safety and maintenance. With its location in a region susceptible to climate variability and water resource management challenges, Reynolds Dam serves as a reminder of the importance of ongoing monitoring and maintenance to ensure the safety and efficiency of water infrastructure for irrigation purposes.

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.
