Summary
Built in 1968 by the USDA NRCS, this dam serves multiple purposes including fire protection, stock watering, and small fish pond management. With a dam height of 42 feet and a length of 127 feet, it has a storage capacity of 42 acre-feet and a surface area of 3 acres.
Despite being classified as having a low hazard potential and a moderate risk assessment, Anderson #7 has not undergone a condition assessment and is not currently regulated or inspected by state agencies. The dam features an uncontrolled spillway with a width of 33 feet and has not been modified in recent years. While it does not have an Emergency Action Plan in place, it is important for water resource and climate enthusiasts to monitor the condition of this dam to ensure the safety of the surrounding area and downstream communities.
Located in the Tulsa District and represented by Congressman Frank D. Lucas, Anderson #7 provides valuable water resources for the local community in Woodward, Oklahoma. As an integral part of the regional water infrastructure, it is essential to stay informed about its condition and any potential risks associated with its operation to mitigate any unforeseen disasters and ensure sustainable water 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.
