Lacreek Dam No. 8 dam
Lacreek Dam No. 8
Lacreek Dam No. 8 is a Federal-owned structure located in Bennett, South Dakota, along Lake Creek. Constructed in 1934 by the Fish and Wildlife Service, this Earth-type dam stands at a height of 12 feet and has a hydraulic height of 7 feet, serving primarily as a Fish and Wildlife Pond. With a storage capacity of 4,558 acre-feet, the dam covers a surface area of 481 acres and has a maximum discharge of 2,260 cubic feet per second.
Despite its low hazard potential and satisfactory condition assessment, Lacreek Dam No. 8 is not regulated by the state of South Dakota. The dam is under the jurisdiction of the Department of Interior's Fish and Wildlife Service, which is responsible for its operation, inspection, and enforcement. With a moderate risk assessment rating of 3, the dam poses a manageable risk, and emergency preparedness measures are in place to ensure the safety of the surrounding area in case of any unforeseen events.
In addition to providing vital water resources for wildlife and recreation, Lacreek Dam No. 8 offers a glimpse into the intricate network of dams and reservoirs that play a crucial role in managing water supply and mitigating the effects of climate change. As a key component of the St. Paul District's infrastructure, this dam exemplifies the importance of sustainable water management practices in sustaining ecosystems and supporting biodiversity in the region.

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 Lacreek Dam No. 8
Where does the data for Lacreek Dam No. 8 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.
