Summary
Built in 1940, this dam stands at a height of 30 feet and has a storage capacity of 100 acre-feet, with a normal operating level of 50 acre-feet. The dam serves a primary purpose of "Other" and is regulated by the Oklahoma Water Resources Board, with state permitting, inspection, and enforcement in place.
Despite being rated as a low hazard potential structure, Humble Banks No 1 poses a very high risk, with a risk assessment score of 1. The dam features a controlled spillway and a single valve outlet gate. The last inspection was conducted in June 2002, with a frequency of every 5 years. While the condition assessment is not rated, the dam is in need of risk management measures to address the high-risk potential associated with its current state.
Water resource and climate enthusiasts will find interest in the unique characteristics and risk profile of Humble Banks No 1. The dam's location, design, and operational aspects provide valuable insights into the challenges and opportunities in managing water resources in Oklahoma. As climate change impacts continue to affect water availability and infrastructure resilience, understanding and addressing the risks associated with dams like Humble Banks No 1 becomes increasingly important for sustainable water management practices.

Dam Data Reference
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.
