Summary
Completed in 1968, this dam serves primarily for irrigation purposes, with a maximum storage capacity of 96 acre-feet and a normal storage capacity of 60 acre-feet. It stands at a height of 24 feet and has a hydraulic height of 21 feet, with a total length of 485 feet. The dam is regulated, inspected, and enforced by the Oklahoma Water Resources Board, ensuring its safety and compliance with state regulations.
Despite its low hazard potential, Isom No 2 is classified as having a very high risk level, signifying the importance of proper risk management measures and maintenance. The dam features a controlled spillway with a width of 1 foot and an outlet gate with a single valve. The last inspection was conducted in June 2002, with a scheduled inspection frequency of 5 years. While the condition assessment is currently not rated, the dam is equipped with emergency action plans and measures to mitigate potential risks and ensure public safety in the event of any emergency situations. The dam remains a vital water resource infrastructure for the local community, contributing to the irrigation needs 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.
