Manston Slough dam
Manston Slough
Manston Slough is a significant water resource in Minnesota, situated in Wilkin County near the city of Georgetown. Owned and regulated by local government authorities, the slough serves as a Fish and Wildlife Pond, with a primary dam type of Earth and a hydraulic height of 5 feet. Completed in 2015, the slough has a storage capacity of 21,414 acre-feet and covers a surface area of 6,043 acres, providing essential habitat for various species of fish and wildlife.
Managed by the Minnesota Department of Natural Resources, Manston Slough plays a crucial role in maintaining the ecological balance in the area. With a low hazard potential and a condition assessment of "Not Rated", the slough is regularly inspected to ensure its structural integrity and functionality. Despite its modest size, the slough contributes to the overall health of the Buffalo River South Branch watershed and is a key component of the local ecosystem.
For water resource and climate enthusiasts, Manston Slough offers a fascinating example of sustainable water management and conservation efforts in Minnesota. With its strategic location and purposeful design, the slough serves as a vital habitat for wildlife and a reliable source of water storage for the surrounding area. As climate change continues to impact water resources, the preservation and proper management of sites like Manston Slough are essential for ensuring the continued health and resilience of our ecosystems.

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.
Plan around the weather

About Manston Slough
Where does the data for Manston Slough 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.
