Cossayuna Lake boat launch
Cossayuna Lake
Cossayuna Lake is a relatively small body of water, with a surface area of 247 acres. The lake is located in the town of Argyle, in Washington County, New York. The lake is known for its clear waters and abundance of fish, making it a popular destination for anglers.
The New York State Department of Environmental Conservation (DEC) manages the Cossayuna Lake and has established certain regulations for watercraft use. All motorized boats must be registered with the DEC and display a valid registration sticker. Additionally, all vessels must comply with the state's boating safety laws and regulations.
In summary, the Cossayuna Lake boat ramp is a 20-feet wide concrete ramp that provides access to Cossayuna Lake, a 247-acre body of water located in the town of Argyle, New York. The ramp can accommodate small to medium-sized boats, canoes, and kayaks. The lake is managed by the New York State Department of Environmental Conservation, and all motorized boats must be registered and comply with safety laws and regulations.

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