Summary
Completed in 1960, this earth dam stands at a height of 19 feet and serves the primary purpose of flood risk reduction along the TR-WEST CR river. With a storage capacity of 50 acre-feet and a normal storage level of 30 acre-feet, Bradshaw No.2 boasts a controlled spillway and a valve outlet gate for water release.
Although rated as having a low hazard potential, the risk assessment for Bradshaw No.2 indicates a very high risk level, with a DSAC assigned date yet to be determined. The dam's condition is currently not rated, with the last inspection conducted in December 2010. Despite the lack of recent assessments, state jurisdiction and regulation by the OWRB ensure that the dam undergoes regular inspections, permitting, and enforcement to maintain its structural integrity and safety standards.
Water resource and climate enthusiasts interested in the operation and maintenance of flood risk reduction structures like Bradshaw No.2 will find this dam's design and construction details, as well as its risk assessment and regulatory oversight, to be of significant interest. The dam's location in Ellis, Oklahoma, its historical completion in 1960, and its association with the Tulsa District of the USACE provide valuable insights into the management of water resources in the region.

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.
