Pomme De Terre Lake dam
Pomme De Terre Lake
Pomme De Terre Lake, located in Barrett, Minnesota, is a stunning reservoir on the Pomme De Terre River managed by the Minnesota Department of Natural Resources. Primarily used for recreation, this concrete gravity dam stands at 10 feet high and has a hydraulic height of 2.6 feet, providing a storage capacity of 23,000 acre-feet. With a surface area of 1,948 acres and a drainage area of 175 square miles, the lake offers ample opportunities for water-based activities and scenic views.
Despite its low hazard potential, Pomme De Terre Lake is subject to regular state inspection, enforcement, and permitting by the Minnesota DNR's Environmental and Water Resources division. The dam's condition was last assessed as satisfactory in 2013, and it has since undergone routine inspections to ensure public safety. With a moderate risk rating, the reservoir is equipped with an uncontrolled spillway and a width of 56 feet to manage water levels during heavy rainfall events.
Water resource and climate enthusiasts will appreciate Pomme De Terre Lake's vital role in providing recreational opportunities and supporting local ecosystems in Grant County, Minnesota. As a beloved destination for boating, fishing, and wildlife observation, this reservoir serves as a valuable water resource within the region. With its state-regulated operations and commitment to safety, Pomme De Terre Lake stands as a well-maintained and cherished asset for the community.

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 Pomme De Terre Lake
Where does the data for Pomme De Terre Lake 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.
