Summary
This dam, situated on TR-CHIGLEY SANDY CREEK, serves multiple purposes and has a storage capacity of 80 acre-feet. With a controlled spillway and a low hazard potential, this dam is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular inspections, enforcement, and permitting to ensure its structural integrity and public safety.
Despite its age, Oknoname 099001 remains in good condition with a very high risk assessment rating of 1. The dam has a valve outlet gate and a surface area of 12 acres, providing essential water resource management for the area. Although it has not been modified in recent years and its condition assessment is not rated, the dam's risk management measures are in place to address any potential issues that may arise. Overall, Oknoname 099001 is an important infrastructure within the Fort Worth District, contributing to water supply and flood control efforts in the region.
With its strategic location in Davis, Oklahoma, Oknoname 099001 is a vital component of the local water management system. The dam's association with the Federal government is limited, but its state jurisdiction and regulatory oversight ensure proper operation and maintenance. As a significant structure on TR-CHIGLEY SANDY CREEK, this earth dam plays a crucial role in the area's water storage and management, highlighting the intersection of climate resilience and water resource sustainability.

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.
