Pittsburg Lake Reservoir Report
Last Updated: February 23, 2026
Pittsburg Lake, located in Pittsburg, Oklahoma, is a key water resource managed by the local government for water supply purposes.
Summary
Built in 1908, this Earth dam stands at a height of 24 feet, with a storage capacity of 424 acre-feet and a surface area of 31 acres. The dam controls the flow of Chum Creek and serves as a critical water source for the region.
The dam's spillway, measuring 1 foot in width, ensures controlled water discharge, with a maximum capacity of 400 cubic feet per second. Despite being classified as having a high hazard potential, the dam's condition is assessed as fair, with regular inspections and enforcement by the Oklahoma Water Resources Board. The risk assessment for Pittsburg Lake indicates a very high risk level, emphasizing the importance of proactive risk management measures to safeguard the surrounding community and environment.
As a focal point for water supply in the region, Pittsburg Lake plays a crucial role in water resource management and climate resilience efforts. With its rich history dating back over a century, the dam continues to provide essential water storage and regulation services, highlighting the importance of sustainable infrastructure for meeting the water needs of local communities in Oklahoma.

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.
