Summary

Completed in 1964, the Redland dam is an earth structure with a height of 27 feet and a length of 380 feet, providing a storage capacity of 41 acre-feet. This low hazard potential dam has a fair condition assessment as of June 2018 and is regularly inspected every 5 years to ensure its safety.

Situated on Redland Draw, this dam serves as a critical resource in the region, with a primary purpose of safeguarding against wildfires and supporting livestock and aquatic life. Despite its modest surface area of 4 acres and limited drainage area, Redland plays a significant role in the local ecosystem by providing essential water storage and management. Additionally, the dam's uncontrolled spillway and lack of outlet gates indicate a simplistic yet effective design for its intended functions.

With its moderate risk assessment and fair condition, Redland remains a vital component of the water resource infrastructure in Washakie County. As climate change continues to impact water availability and distribution, structures like Redland play a crucial role in maintaining water security and resiliency in the face of evolving environmental challenges. By ensuring regular inspections and maintenance, Redland can continue to fulfill its intended purposes for years to come, serving as a testament to the importance of sustainable water resource management 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.
