Oknoname 111045 dam
Oknoname 111045
Oknoname 111045 is a privately-owned dam located in Okmulgee, Oklahoma, specifically in the city of Henryetta. Built in 1940, this earth dam stands at a height of 25 feet and spans a length of 3190 feet, with a storage capacity of 50 acre-feet. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular inspections, with the last inspection dating back to August 2011. The dam's spillway is of the controlled type, with a width of 1 foot, and the hazard potential is classified as low.
Situated on TR-COAL CREEK, Oknoname 111045 serves a primary purpose that is classified as "Other", with the dam type being earth and the core made of stone. The dam's maximum discharge capacity is 310 cubic feet per second and it features a single valve outlet gate. Despite being rated as low hazard potential, the risk assessment for this dam is very high, with a risk level of 1. The dam does not have a Emergency Action Plan (EAP) in place and is not under the jurisdiction of the US Army Corps of Engineers (USACE), thus making it essential for the private owner to ensure proper risk management measures are in place to mitigate any potential hazards.

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 Oknoname 111045
Where does the data for Oknoname 111045 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.
