About this dam

Two Inlets Lake

Two Inlets Lake in Minnesota is a picturesque body of water nestled in Becker County, offering a serene escape for water resource and climate enthusiasts. This man-made lake was completed in 1938 with a primary purpose of recreation, providing a surface area of 600 acres for outdoor activities. The dam, constructed of concrete with a gravity design, stands at a height of 11 feet and has a maximum storage capacity of 4,000 acre-feet.

With a low hazard potential and fair condition assessment, Two Inlets Lake is considered a relatively safe and well-maintained water resource. The controlled spillway, measuring 50 feet in width, helps manage water levels and mitigate flooding risks. The lake is regulated by the Minnesota Department of Natural Resources Environmental and Water Resources division, ensuring that state permitting, inspection, and enforcement measures are in place to protect the surrounding environment.

Surrounded by the tranquil beauty of nature, Two Inlets Lake offers a peaceful retreat for visitors to enjoy fishing, boating, and other recreational activities. Whether you're seeking a relaxing day on the water or a chance to explore the local wildlife, this charming lake provides an ideal setting for nature lovers to appreciate Minnesota's diverse landscape and water resources.

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.

FAQ

About Two Inlets Lake

Where does the data for Two Inlets 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.
