Summary
Managed by the Oklahoma Water Resources Board, Prentice stands at a height of 26 feet and has a storage capacity of 160 acre-feet, serving the primary purpose of irrigation for the surrounding area. The dam, primarily made of earth and stone, spans 861 feet with a controlled spillway and a single valve outlet gate.
Despite being classified as having a low hazard potential, Prentice poses a very high risk due to its location and structure. The dam has not been rated for its condition since its last inspection in 1999, with an inspection frequency of every 5 years. The risk assessment for Prentice is ranked at the highest level (1), indicating the urgent need for risk management measures and the potential for significant consequences in the event of a failure.
Water resource and climate enthusiasts will be intrigued by the data surrounding Prentice, a vital irrigation structure in Oklahoma. With its historical significance and the urgent need for updated risk assessment and management, Prentice serves as a focal point for understanding the intersection of water resource management, infrastructure maintenance, and climate resiliency 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.
