Summary

Standing at a height of 16 feet with a length of 700 feet, the dam has a primary purpose classified as "Other" and boasts a maximum storage capacity of 66 acre-feet. The dam is situated on the TR-BIG SANDY CREEK river and falls under the jurisdiction of the Tulsa District of the US Army Corps of Engineers.

Despite its relatively modest size, Newman Dam No 4 poses a high risk, with a hazard potential that is currently not available. The dam has not been rated for its condition assessment, and there is limited information available on its emergency preparedness and risk management measures. The last inspection of the dam took place in September 1972, and it is unclear if any modifications or upgrades have been made since then. While the dam does not have a spillway, it does have one outlet gate.

For water resource and climate enthusiasts, Newman Dam No 4 presents an intriguing case study in dam infrastructure and management. With its unique design features and high risk classification, this privately owned dam serves as a reminder of the importance of regular inspections, maintenance, and emergency preparedness in ensuring the safety and functionality of water storage structures. Further research and monitoring of Newman Dam No 4 could provide valuable insights into the challenges and opportunities of managing small-scale dams in a changing climate.

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.
