Summary

Constructed in 1920, this earth-type dam with stone core rests on rock and soil foundations, spanning 1000 feet in length and reaching a height of 20.7 feet. Serving multiple purposes beyond its primary one, Oxford plays a crucial role in regulating water flow and storage in the region, while also contributing to flood control efforts.

Managed by a private entity, the dam is subject to state regulations, inspections, and enforcement to ensure its integrity and safety. Despite being classified as having a low hazard potential, the condition assessment in 2017 reported Oxford to be in fair condition. The spillway, with a width of 10 feet, is uncontrolled, and the risk assessment for the dam is moderate. With a drainage area of 0.9 square miles and located near Wickiup Creek and Bear Creek, Oxford remains a key component of the local water infrastructure.

As water resource and climate enthusiasts continue to monitor and assess the impact of dams on the environment, Oxford stands out as a significant structure in the region. With its historical significance and ongoing role in water management, the dam serves as a reminder of the delicate balance between harnessing water resources for human needs and safeguarding the environment for future generations. As efforts to mitigate climate change and adapt to its effects intensify, understanding the role of structures like Oxford becomes increasingly crucial in sustainable water resource management.

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.
