Summary
Built in 1980 for grade stabilization purposes, this earth-type dam stands at a height of 31 feet with a structural height of 33 feet and a length of 530 feet. It holds a storage capacity of 41 acre-feet and serves to stabilize the flow of TR-Sampson Creek, a river or stream in the area.
Despite being privately owned and not regulated by the state, White Oak Twpca-29-6003-081-003-5 poses a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. With a moderate risk assessment score of 3, this dam has not had an emergency action plan (EAP) prepared or regularly updated. The dam's spillway type is uncontrolled, and it has a maximum discharge capacity of 60 cubic feet per second, serving a drainage area of 145 acres.
Overall, White Oak Twpca-29-6003-081-003-5 plays a crucial role in maintaining the stability of the surrounding area and managing water flow in TR-Sampson Creek. Its presence highlights the importance of private infrastructure in water resource management and underscores the need for continued monitoring and maintenance to ensure the safety and functionality of such structures in the face of changing climate conditions.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
