Summary
This private dam serves a primary purpose that is classified as "Other," with a normal storage capacity of 42.5 acre-feet and a maximum storage of 74 acre-feet. The dam is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, with the last one conducted in November 2010.
Despite being classified as having a low hazard potential, Webb Dam is deemed to have a very high risk level, with a risk assessment rating of 1. The dam features a controlled spillway with a width of 1 foot and one outlet valve. The surrounding area has a surface area of 7.2 acres and a drainage area of 0.63 square miles. While the condition assessment of the dam is currently marked as "Not Rated," the risk management measures and emergency action plan status remain undisclosed.
Water resource and climate enthusiasts may find Webb Dam to be a fascinating subject of study due to its unique design as an earth dam and its location within the Tulsa District of Oklahoma. The dam's construction and management by a private entity, along with its state-regulated status and risk assessment, offer valuable insights into the complexities of maintaining water infrastructure in an environmentally conscious manner. As a low-hazard dam with a high-risk assessment, Webb Dam serves as a reminder of the importance of regular inspections and risk management strategies in ensuring the safety and sustainability of water resources in the region.

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.
