Eros Data Center Dam dam
Eros Data Center Dam
The Eros Data Center Dam in South Dakota, completed in 1972, is a federal-owned Earth dam with a height of 31 feet and a storage capacity of 96 acre-feet. Located on the tributary of W. Pipestone Creek, this dam serves multiple purposes including flood control, water supply, and recreation. With a low hazard potential and a condition assessment of "Not Rated," the dam provides essential infrastructure for managing water resources in the region.
Despite not being state-regulated, the Eros Data Center Dam plays a crucial role in the local water management system, with a maximum discharge capacity of 540 cubic feet per second. The dam's location in Minnehaha County, South Dakota, underscores its significance in protecting downstream areas from potential flooding events. Climate enthusiasts and water resource experts alike can appreciate the engineering and environmental considerations that go into maintaining and operating this key piece of infrastructure.
While the dam's emergency action plan and risk assessment information are not readily available, the Eros Data Center Dam stands as a testament to the importance of sustainable water resource management in the face of changing climate patterns. As climate change continues to impact water availability and quality, understanding and maintaining critical infrastructure like the Eros Data Center Dam will be essential for ensuring the resilience of communities and ecosystems 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 Eros Data Center Dam
Where does the data for Eros Data Center 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.
