Lake Berry Dam dam
Lake Berry Dam
Lake Berry Dam, located in Gregory, South Dakota, stands as a vital state-regulated water resource on Willow Creek. Built in 1940, this earth-type dam boasts a height of 21 feet and a storage capacity of 495 acre-feet, providing essential water supply and flood control benefits to the region. With a low hazard potential and a condition assessment that is currently not rated, Lake Berry Dam serves as a crucial infrastructure for water management in the area.
Managed by the South Dakota State agency, the dam undergoes regular inspections with an inspection frequency of 3 years, ensuring its structural integrity and safety. While the dam's Emergency Action Plan (EAP) status and other risk assessment measures are not specified in the data, the presence of state permitting, inspection, and enforcement mechanisms points to a proactive approach in ensuring the safety and efficiency of Lake Berry Dam. As climate change impacts water resources globally, the role of dams like Lake Berry becomes increasingly significant in safeguarding water supply and mitigating potential risks associated with extreme weather events.
In the realm of water resource and climate enthusiasts, Lake Berry Dam represents a critical piece of infrastructure in the sustainable management of water in South Dakota. With its historical significance, state regulation, and essential functions in water storage and flood control, the dam serves as a beacon of resilience in the face of changing climate patterns. As stakeholders continue to monitor and assess the dam's condition and safety measures, Lake Berry Dam stands as a testament to the importance of proactive water resource management in the context of a changing climate landscape.

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 Lake Berry Dam
Where does the data for Lake Berry 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.
