O'Brien Reservoir
According to the Minnesota Department of Natural Resources, the boat ramp at O'Brien Lake is a concrete ramp that is 20 feet wide. It services O'Brien Lake, which is a 299-acre lake located in Crow Wing County. The lake has a maximum depth of 46 feet and is primarily used for fishing and recreational boating.
The DNR states that motorized watercraft are allowed on O'Brien Lake, as well as canoes, kayaks, and other non-motorized watercraft. However, there are no wake restrictions on the lake, so it is important for boaters to be aware of their wake and ensure that they are not causing damage or disturbance to other boaters or shoreline structures.
It is important to note that the information provided is accurate as of the time of research and is subject to change. Boaters should always consult the latest regulations and guidelines from the Minnesota DNR before launching their watercraft.

Boating safety & etiquette
- Check the conditions before you launch
- Use the streamflow numbers, weather, and wind forecast on this page. High-cfs whitewater requires whitewater-specific craft and skill.
- Wear your life jacket
- Statistically the single biggest survival factor in a boating incident. State law often requires one per passenger.
- File a float plan
- Tell someone on shore your put-in, take-out, and expected return time. Especially for multi-day or remote trips.
- Yield at the ramp
- Prep gear in the parking lot, not on the ramp. Launch and clear quickly so others can use the lane.
- Clean, drain, dry
- Inspect, clean, drain and dry your boat between waters to prevent the spread of aquatic invasive species.
Set push alerts in the Snoflo app

About O'Brien Reservoir
Can I launch a motorboat here?
Most Snoflo-tracked launches support motorboats; check the operator for any horsepower restrictions, paddle-only zones, or seasonal closures.
How fresh is the streamflow data?
USGS streamgauges report continuously (every 15 minutes); the table on this page pulls the latest reading at page load.
Is there a fee?
Many federal and state boat launches charge a day-use fee. Check the operator's site before driving out.
What boat is right for these conditions?
Use the nearby streamflow numbers and river-run panel on this page to gauge current conditions. Wider, slower water is friendly for casual paddling and powerboats; high-cfs whitewater requires whitewater-specific craft and skill.
Can I get alerts when conditions change?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this launch, set a threshold (discharge, wind), and you'll get a push the moment it crosses.
