Summary

This privately owned dam, standing at a height of 12 feet and stretching 665 feet in length, holds a storage capacity of 88 acre-feet and covers a surface area of 9.8 acres. Despite its relatively small size, Oasis Lake Dam plays a significant role in regulating the flow of Oasis Creek and maintaining water levels for various purposes.

The primary purpose of Oasis Lake Dam is listed as "Other," indicating its multifaceted role in water resource management. This earth dam, with a buttress core type, features uncontrolled spillways and an uncontrolled outlet gate. While the dam is not currently rated for condition assessment, it is inspected periodically to ensure its structural integrity and functionality. The risk assessment for Oasis Lake Dam is categorized as moderate, highlighting the importance of ongoing monitoring and maintenance to mitigate potential hazards and ensure the safety of surrounding communities and ecosystems.

With its strategic location and critical function in water regulation, Oasis Lake Dam stands as a testament to the significance of infrastructure in addressing the challenges posed by climate change and shifting environmental conditions. As water resource and climate enthusiasts, understanding the design, purpose, and risk assessment of structures like Oasis Lake Dam is essential for fostering sustainable practices and safeguarding our natural resources 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.
