Hawell Robert & Ann dam
Hawell Robert & Ann
Hawell Robert & Ann is a privately-owned dam located in LIMESTONE GAP, Atoka, Oklahoma. Built in 1960, this earth dam stands at 25 feet tall and spans a length of 1000 feet. The primary purpose of this structure is classified as 'Other' with a storage capacity of 166 acre-feet. The dam is regulated and inspected by the Oklahoma Water Resources Board, ensuring compliance with state regulations for safety and maintenance.
The dam on TR-BUCK CREEK is equipped with a controlled spillway and a single valve outlet gate. Despite the low hazard potential and a risk assessment ranking of 'Very High (1)', the condition of Hawell Robert & Ann is currently listed as 'Not Rated'. The last inspection was conducted in April 2010, with a frequency of every 5 years. While emergency action plans and risk management measures are not specified, the dam remains under state jurisdiction and enforcement to mitigate potential risks and ensure the safety of surrounding communities and water resources.
With a surface area of 19 acres and a normal storage capacity of 146 acre-feet, Hawell Robert & Ann plays a critical role in water resource management and flood control in the area. As climate change continues to impact water availability and extreme weather events, the dam's structural integrity and maintenance will be vital in safeguarding downstream communities and ecosystems. Enthusiasts interested in water resource management and climate resilience can appreciate the importance of Hawell Robert & Ann in mitigating potential risks and ensuring sustainable water management practices in Atoka, Oklahoma.

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 Hawell Robert & Ann
Where does the data for Hawell Robert & Ann 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.
