City Of Blackwell dam
City Of Blackwell
City of Blackwell, located in Kay, Oklahoma, is home to a crucial water supply dam along the Chickaskia River. 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.

About City Of Blackwell
Where does the data for City Of Blackwell come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card below for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.

Condition Assessment
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.
