Perch Lake dam
Perch Lake
Perch Lake, located in Carlton, Minnesota, is a picturesque body of water with a storage capacity of 3,801 acre-feet. Managed by the Department of the Interior's Bureau of Indian Affairs, this lake has a dam height of 7 feet and is classified as having an undetermined hazard potential. Despite its small size and lack of detailed information on its condition assessment, Perch Lake serves as an important water resource for the local community.
While specific details about the purpose of Perch Lake and its associated structures are not provided, its tranquil setting and natural beauty make it a popular destination for water resource and climate enthusiasts. With a latitude of 46.6827 and a longitude of -92.69349, this lake offers a serene environment for fishing, boating, and other recreational activities. As a part of the St. Paul District under the purview of the U.S. Army Corps of Engineers, Perch Lake remains a vital part of the region's ecosystem.
Although Perch Lake's risk assessment and management measures are not readily available, its status as a federally managed water body underscores its importance in the region. As part of a larger network of lakes and waterways in Minnesota, Perch Lake contributes to the overall environmental health and sustainability of the area. For water resource and climate enthusiasts, this serene lake offers a glimpse into the natural beauty and ecological significance of the region.
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 Perch Lake
Where does the data for Perch 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 Undetermined 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.
