Reservoir report

Minnesota has over 15,000 lakes and reservoirs, with the largest being Lake of the Woods, Rainy Lake, and Lake Vermilion. These reservoirs are primarily fed by streams and rivers such as the Mississippi, St. Croix, and Red River. Snowpack in the northern part of the state is crucial for maintaining water levels in these reservoirs during the dry summer months. However, drought conditions can negatively impact water levels, as was the case in the summer of 2021 when Lake Minnetonka recorded its lowest water level in 80 years. The hydrology of the area is influenced by the state's geography, which includes rolling hills and flat plains. Seasonal trends include high water levels in the spring due to snowmelt and lower levels in the summer months. Overall, reservoirs and dams play an important role in providing water for agriculture, industry, and recreation in Minnesota.

Reservoir FAQ

About Minnesota dams & reservoirs

Where does the Minnesota dam data come from?

The U.S. Army Corps of Engineers National Inventory of Dams (NID) plus state water-resource agencies. Snoflo joins these public records with live USGS streamgauge readings downstream where available. The NID is the canonical federal dam registry.

What does Hazard Potential mean?

USACE classifies every dam by what would happen if it failed: Low (no loss of life expected, minimal economic damage), Significant (no loss of life but economic, environmental, or lifeline damage), High (loss of life expected). It's a downstream-consequence rating, not a likelihood of failure.

What is Normal Storage in acre-feet?

The volume of water the reservoir holds at its normal operating level, measured in acre-feet. One acre-foot is about 325,851 gallons or 1,233 cubic meters — the amount needed to cover one acre to a depth of one foot.

Why are some Minnesota dams missing storage or height data?

USACE NID records can have gaps for small or older dams that pre-date federal reporting requirements. Snoflo surfaces whatever the canonical record contains. If a dam you care about has incomplete data, contact the operating agency or USACE for updates.

Can I see live water levels?

Yes — tap any dam name to open its detail page, which pulls live storage data from USGS streamgauges or operating-agency feeds where available. Historical levels and seasonal averages are also shown.

Why does Minnesota have so many dams?

The U.S. has over 90,000 dams — most built between 1930 and 1980 during the federal water-development era. Minnesota's count reflects a combination of agricultural irrigation needs, flood control, hydropower, and recreation. The "Built by decade" chart above shows the timeline.
