Warren Diversion dam
Warren Diversion
Warren Diversion, also known as Snake River, is a local government-owned structure in Warren, Minnesota, designed by the USDA NRCS to reduce flood risk in the area. Completed in 2003, this buttress dam stands at 30 feet high and spans 4000 feet along the Snake River. With a storage capacity of 2000 acre-feet and a normal storage level of 15 feet, the dam plays a crucial role in mitigating the impact of high water levels in the region.
Managed by the Minnesota Department of Natural Resources, the Warren Diversion is regulated, inspected, and enforced to ensure its structural integrity and functionality. Its controlled spillway, slide gates, and satisfactory condition assessment contribute to its significant hazard potential rating and very high risk assessment score. In the event of an emergency, the dam's emergency action plan and inundation maps will guide appropriate responses and measures to protect the surrounding area from potential risks.
As a key component in the flood risk reduction strategy for the Snake River, Warren Diversion serves as a vital infrastructure for water resource management in Marshall County, Minnesota. Its strategic location, efficient design, and adherence to regulatory standards demonstrate a commitment to safeguarding the community and environment from the adverse impacts of extreme weather events and water-related disasters.
Dam data reference
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 Warren Diversion
Where does the data for Warren Diversion 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 Significant 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.
