Summary
Constructed in 1960 by USDA NRCS, this structure stands at 37 feet high with a hydraulic height of 33 feet and a length of 300 feet. The dam has a storage capacity of 220 acre-feet and a normal storage level of 45 acre-feet, serving primarily for purposes classified as "Other."
Managed by the Oklahoma Water Resources Board, Taylor No 4 is equipped with a controlled spillway and a single valve outlet gate. Despite being rated as having a low hazard potential and not yet assessed for overall condition, the dam is considered to have a very high risk level. The last inspection conducted on the site was in June 2005, with a scheduled inspection frequency of every 5 years. With its strategic location and vital role in water resource management, Taylor No 4 serves as a significant structure in the region's climate resilience efforts.
Overall, Taylor No 4 stands as a crucial element in the water infrastructure of Dewey County, Oklahoma, providing essential storage and flood control along the TR-Canadian River. As a privately-owned dam with state regulation and oversight, its design and construction by USDA NRCS ensure its structural integrity and functionality. With a focus on risk management and emergency preparedness, Taylor No 4 plays a key role in safeguarding the surrounding community and environment from potential water-related hazards and emergencies.

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.
