Summary

5 Wetland serves as a vital water resource for the region. Completed in 2003, this Earth dam stands at a height of 14 feet and boasts a storage capacity of 284 acre-feet, providing essential fire protection and stock watering capabilities. The wetland covers an impressive surface area of 48.1 acres and is situated along the Red Wash Creek, making it a key feature in the local ecosystem.

Managed by the Natural Resources Conservation Service and designer Mark Opitz, the Red Wash No. 5 Wetland is a state-regulated structure with inspection, permitting, and enforcement protocols in place. Despite a poor condition assessment in 2018, the wetland poses a low hazard potential and is equipped with an uncontrolled spillway for water management. Its strategic location on HWY 789 ensures easy access for maintenance and emergency response, further enhancing its value as a water resource for the community.

With a moderate risk assessment rating, the Red Wash No. 5 Wetland offers a unique blend of functionality and conservation efforts. From supporting local wildlife to providing essential water storage, this wetland represents a harmonious balance between human needs and environmental stewardship. As climate change continues to impact water resources, structures like the Red Wash No. 5 Wetland play a crucial role in maintaining ecological balance and safeguarding water supplies for future generations.

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.
