The honest framing
The seasonal set on this site has covered spring cold water and fall for a while. This page covers the part nobody had written down: what actually happens here between November and April.
Two things to be clear about up front. Paddle Greene has never field visited a launch in the off season, so this is desk research about closures and general practice, not observation. And off-season paddling is not a harder version of summer paddling - it is a different activity, with different gear, different training, and different consequences for getting it wrong. Nothing here is a recommendation to go.
What closes, and what that means
Some of this is a rule rather than a judgment call.
- Schoharie Reservoir is closed to boating outside roughly May 1 to October 31, sunrise to sunset, per NYC DEP. Conditions are irrelevant: outside the window, you cannot legally launch. See permits and fees for what the season requires even inside it.
- North-South Lake and the nearby state parks run seasonal day-use operations. Gates, fee collection, restrooms, and plowing all change or stop. Season dates move year to year and need confirming with the managing agency.
- Rentals are summer businesses. Assume nothing is renting boats in February.
What we genuinely do not know is which Hudson launches stay physically open and plowed through the winter, and whether their parking areas are gated. That is on the open questions list, and it is exactly the sort of thing a local would know offhand.
Cold water sets the rules
The spring cold-water guide covers this properly and is worth reading in full rather than summarizing badly here. The short version: cold shock and hypothermia are the hazard, not the air temperature, and the gap between how a sunny April day feels and what the water will do to you is where people get caught out.
In the deeper off season the same logic applies with less margin. Water in the thirties and forties gives you very little time if you go in, and there are fewer people around to notice.
Dress for the water, not the air, from roughly October through May.
Ice
The tidal Hudson along Greene County moves constantly and rarely locks up entirely, which is why winter paddling is not simply impossible here. That does not make it benign:
- Ice forms in sheltered margins, coves, and creek mouths even while the main channel is open.
- It drifts with the tide, so the water you paddled out through may not be the water you come back to.
- The Coast Guard maintains a broken shipping channel through winter ice, which means moving ice and commercial traffic in the same place.
- Shoreline ice can make your planned exit unusable, which is the failure that turns an outing into an emergency.
The mountaintop lakes are a different matter and freeze properly. Ice-in and ice-out timing varies year to year and we have not tracked it.
Shorter days, emptier places
Practical things that change:
- Daylight. Plan around an early sunset and get off the water well before it. Bring light.
- Nobody around. In summer a mistake at a busy launch is embarrassing; in January it may go unnoticed. Tell someone your plan and stick to it.
- Facilities. Restrooms close, water gets shut off, and there is often nowhere to warm up nearby.
- Roads. Getting to a mountaintop launch is its own problem in winter, and the tides and gauges checks matter as much as ever.
If you are considering it
The bar is genuinely different: immersion gear appropriate to the water temperature, cold-water training and a practised self-rescue, a partner, a conservative plan close to shore and close to the launch, and dry clothes waiting in the car.
If you do not have all of that, the answer is to wait. There is no paddle on this water worth the alternative, and the calm-water options will still be there in May.
If you do paddle here in the off season and know what stays open, tell us. We would rather publish your firsthand knowledge than keep guessing at it.
