Waterbnot Ratedy Dam dam
Waterbnot Ratedy Dam
Waterbnot Ratedy Dam, located in Gregory, South Dakota, is a privately owned structure that plays a crucial role in regulating the flow of the Tributary Ponca Creek. Built in 1976, this Earth type dam stands at a height of 60 feet and has a length of 1100 feet, with a storage capacity of 900 acre-feet. Despite being marked as "Not Rated" in terms of condition assessment, the hazard potential of the dam is classified as low, providing a sense of security to the surrounding community.
Managed by the South Dakota Department of Agriculture and Natural Resources, Waterbnot Ratedy Dam is subject to state regulation, inspection, and enforcement. The dam has been designed to withstand maximum discharges and is equipped with outlet gates for controlled water release. Although the dam has not been updated or modified in recent years, it continues to serve its primary purpose effectively, ensuring water resource management and flood control in the area.
With its strategic location and vital role in water management, Waterbnot Ratedy Dam stands as a testament to human ingenuity in harnessing natural resources for the benefit of society. The dam's low hazard potential, coupled with state oversight and regular inspections, instills confidence in its ability to withstand potential risks and protect the local community from adverse impacts of climate change. For water resource and climate enthusiasts, Waterbnot Ratedy Dam serves as a noteworthy example of infrastructure designed to adapt to changing environmental conditions and serve the needs of both people and the environment.

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 Waterbnot Ratedy Dam
Where does the data for Waterbnot Ratedy Dam 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.
