Summary
Completed in 1969, this dam stands at a height of 36 feet with a hydraulic height of 32 feet, providing a maximum storage capacity of 552 acre-feet and a normal storage capacity of 82 acre-feet. The dam spans 1460 feet in length and covers a surface area of 24 acres, helping to mitigate the risk of flooding in the region.
With a Hazard Potential rated as high and a Condition Assessment deemed fair, SCS-Tonkawa Creek Site-004 serves as a crucial infrastructure for managing water resources and climate-related risks in the area. The dam features a controlled spillway and one outlet gate for effective water flow control. Despite its age, the dam has been inspected periodically, with the last inspection conducted in September 2010. The risk assessment for this site indicates a very high risk level, underscoring the importance of ongoing monitoring and maintenance to ensure its structural integrity and flood protection capabilities.
Managed by the Natural Resources Conservation Service and state regulatory agencies, this dam plays a vital role in protecting the surrounding community from potential flooding events. As climate change continues to impact weather patterns and water resources, the significance of structures like SCS-Tonkawa Creek Site-004 in mitigating flood risks and safeguarding communities becomes increasingly evident. Through regular inspections, risk assessments, and maintenance efforts, this dam remains a key asset in the region's resilience to water-related 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.
