Chelsea Reservoir No. 1 dam
Chelsea Reservoir No. 1
Chelsea Reservoir No. 1, located in Spencer Creek Cove Oologah, Oklahoma, is a vital water supply resource owned by the local government. Constructed in 1950 by USDA NRCS, this Earth dam stands at a height of 45 feet with a capacity to store 570 acre-feet of water. Its primary purpose is to provide water supply for the region, serving as a crucial source for the surrounding communities.
Managed by the OWRB and regulated by the state, Chelsea Reservoir No. 1 boasts a controlled spillway with a width of 1 foot, ensuring efficient water discharge when necessary. With a hazard potential rated as low and a risk assessment indicating a very high risk level, this reservoir is subject to regular inspections and maintenance to ensure its structural integrity and safety for the public. Despite its age, the dam remains in good condition, with a risk management plan in place to address any potential issues that may arise.
In the event of an emergency, Chelsea Reservoir No. 1 has one valve outlet gate for water release. With a surface area of 22 acres and a maximum discharge rate of 1500 cubic feet per second, this reservoir plays a crucial role in water management and conservation efforts in the region. As climate change continues to impact water resources, the importance of maintaining and safeguarding infrastructure like Chelsea Reservoir No. 1 becomes increasingly significant in ensuring a sustainable water supply for future generations.

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.

About Chelsea Reservoir No. 1
Where does the data for Chelsea Reservoir No. 1 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 above 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.
