Langhorst Pond dam
Langhorst Pond
Langhorst Pond, located in Moose Lake, Minnesota, is a privately owned earth dam built in 1967 by the USDA NRCS for purposes beyond flood control. The dam, standing at a height of 11 feet and stretching 261 feet in length, serves as a water resource for the area, with a storage capacity of 367 acre-feet and a normal storage level of 105 acre-feet. The pond covers an area of 18 acres and has a drainage area of 2.7 square miles, with a maximum discharge capability of 150 cubic feet per second.
Managed by the MNDNR EWR, Langhorst Pond is classified as a low-hazard structure with satisfactory condition assessment as of September 2017. The dam features an uncontrolled spillway and outlet gates, with regular inspections conducted every 8 years to ensure its safety and functionality. The risk assessment for the pond is moderate, indicating a moderate level of potential risk associated with the structure.
Climate and water resource enthusiasts can appreciate Langhorst Pond for its role in providing water storage and management in the region. With its strategic location along the Portage River-TR and its low-hazard potential, the pond serves as a valuable asset for the community, highlighting the importance of sustainable water resource management practices in mitigating the impacts of climate change and ensuring water security for future generations.
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.
Plan around the weather

About Langhorst Pond
Where does the data for Langhorst Pond 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.
