City of Blackwell, located in Kay, Oklahoma, is home to a crucial water supply dam along the Chickaskia River.
Summary
Built in 1950, this buttress-type dam stands at 20 feet in height and stretches 600 feet in length, with a storage capacity of 120 acre-feet. Managed by the Local Government, the dam is regulated and inspected by the Oklahoma Water Resources Board to ensure its functionality and safety for the surrounding community. Despite being classified as having a low hazard potential, the dam is considered to have a very high risk due to its age and the need for regular inspections and maintenance.
With a controlled spillway and a single valve outlet gate, the City of Blackwell dam serves as a vital water resource for the area, supplying water for various purposes. While the dam is in fair condition and has not been rated, its risk assessment remains a top priority. Given its importance to the region, stakeholders must continue to monitor and manage the dam effectively to mitigate any potential risks and ensure its long-term functionality. As a key infrastructure for water supply, the City of Blackwell dam plays a critical role in supporting the community's needs and the surrounding ecosystem, making it an essential feature for water resource and climate enthusiasts to keep an eye on.

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.
