Summary
This dam, standing at a height of 27 feet with a hydraulic height of 23 feet, has a storage capacity of 107 acre-feet and a surface area of 6 acres. The dam is regulated by the Oklahoma Water Resources Board and is subject to regular inspections, with the last recorded inspection taking place in November 2010.
Despite being classified as having a low hazard potential, Oren No 1 is considered to have a very high risk level, with a risk assessment rating of 1. The dam features a controlled spillway and a single valve outlet gate, with no associated structures or locks. While the condition of the dam is currently not rated, it is important for water resource and climate enthusiasts to monitor the ongoing maintenance and risk management measures for Oren No 1 to ensure the safety and effectiveness of its water supply operations for the surrounding area.
With its strategic location on TR-North Elm Creek and proximity to the Tulsa District, Oren No 1 plays a crucial role in providing water for the local community and supporting agricultural activities in Beckham County, Oklahoma. As climate change continues to impact water resources, understanding the infrastructure and risk factors associated with dams like Oren No 1 is essential for sustainable water management practices and resilience in the face of evolving climate challenges.

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.
