Summary
This structure, with a height of 20 feet and a hydraulic height of 17 feet, serves as a crucial water resource along the TR-Little Riv. It has a storage capacity of 198 acre-feet and a maximum discharge of 775 cubic feet per second.
Managed by the Oklahoma Water Resources Board, Gregory Wv has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. Despite its age, the dam has undergone regular inspections with the last one conducted in May 2010. It is equipped with a controlled spillway and a single valve outlet gate. The risk assessment for this dam has been classified as "Very High (1)", prompting the need for effective risk management measures to ensure its continued safety and functionality.
As part of the Fort Worth District, Gregory Wv plays a vital role in water management in the region. With state-regulated permitting, inspection, and enforcement in place, this dam serves as a key infrastructure for water resource and climate enthusiasts to observe and appreciate. Its location and design make it a significant asset in maintaining water supply and managing potential risks associated with its operation.

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.
