Summary

Built in 1970, this earth dam stands at a height of 15 feet and has a storage capacity of 51 acre-feet, with a maximum discharge of 1600 cubic feet per second. The dam serves a primary purpose other than flood control or irrigation, and is regulated by the Oklahoma Water Resources Board.

Despite being rated as having low hazard potential, Weibmuenste John P is considered to have a very high risk due to its location and design. The dam has a controlled spillway with a width of 1 foot and one valve outlet gate. It has not been inspected since August 2006, and its condition is currently not rated. Emergency action plans and risk management measures have not been updated or implemented, raising concerns about the safety and readiness of the dam in case of an emergency.

For water resource and climate enthusiasts, Weibmuenste John P presents an intriguing case study in dam safety and risk assessment. With its outdated inspection records and lack of emergency preparedness measures, this dam serves as a reminder of the importance of regular maintenance and monitoring to prevent potential disasters. As the debate on climate change and its impact on water resources intensifies, ensuring the safety and resilience of critical infrastructure like Weibmuenste John P becomes more crucial than ever.

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.
