Summary
The dam, completed in 1980, stands at 48 feet high and spans 500 feet in length, with a maximum discharge capacity of 2780 cubic feet per second. It serves as a crucial water resource infrastructure in the region, with a storage capacity of 200 acre-feet and a drainage area of 565 square miles.
Managed by the Oklahoma Water Resources Board, Judy Hs is regulated, permitted, inspected, and enforced by the state authorities to ensure its safety and functionality. The dam's primary purpose is classified as 'Other', and its structure is predominantly made of earth and stone materials. Despite not having a condition assessment rating, the dam is equipped with a controlled spillway and a valve outlet gate to manage water flow and maintain normal storage levels. With its strategic location on the TR-DRY BR river, Judy Hs plays a vital role in water resource management and climate resilience efforts in the area.
Given its critical role in water management and the high risk assessment rating, Judy Hs requires regular inspections and potential risk management measures to safeguard against any unforeseen emergencies. The dam's emergency action plan status, inundation maps, and risk management strategies are yet to be fully assessed and implemented, highlighting the need for proactive measures to address any potential safety concerns. As a key asset in the region's water infrastructure, Judy Hs serves as a focal point for water resource and climate enthusiasts to monitor and support sustainable management practices for the future.

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.
