Surry Mountain Lake boat launch
Surry Mountain Lake
Surry Mountain Lake services the body of water known as Surry Mountain Lake itself. This lake is a relatively small body of water, measuring only about 68 acres in size. It is located in the southwestern part of New Hampshire and is part of the Ashuelot River watershed.
The New Hampshire Fish and Game Department manages the lake and its boat ramp. According to their latest information, motorized boats are allowed on the lake, but there is a 10 HP limit. Additionally, non-motorized boats such as canoes, kayaks, and paddleboards are also permitted on the lake.
In summary, Surry Mountain Lake is a concrete boat ramp in Surry, New Hampshire, that services the 68-acre Surry Mountain Lake. The boat ramp is wide enough to accommodate small to medium-sized boats and trailers, and it is managed by the New Hampshire Fish and Game Department. The lake allows motorized boats with a 10 HP limit and non-motorized boats such as canoes, kayaks, and paddleboards.

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
Save Surry Mountain Lake as a favorite, set a discharge threshold or a wind/precipitation alert, and the iOS app will push the moment conditions cross.
About Surry Mountain Lake
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.
