The same rivers that make fine rafting runs for the commercial outfits also offer the biggest water for hard-sided boats. Don't stop the search there, though. The spring thaw swells dozens of great, lesser-known streams and rivers to levels that will satisfy any riverdog. Check out flashers like the Boreas River, Mill Creek, and the notorious Trout Brook.
Whitewater Rivers
Hudson
The Hudson is considered to be one of the best season-long kayak runs in
the Adirondacks. Starting below the Lake Abanake Dam, adventurous paddlers
can tackle the hard class V Otter Slide at the beginning of the Indian River,
or opt for the easier start at the rafters' put-in. Be aware that the
Indian River is a real challenge at all times, but is ONLY runnable during
very high water or dam releases. The Hudson itself is navigable through
the summer on dam release days and when the North Creek gauge registers 3.5'
or higher.
Be aware that many folks run the Hudson in its milder seasons in C1s, but
that open canoes CANNOT make this at any time of year (mostly due to the
hard, shallow rapids of the Indian River, but a few of the drops in the Hudson
itself would stop all but the very best open canoe paddlers.
Schroon River
The Schroon River offers a wild ride from below the Starbuckville Dam to
exit 24 along with a long stretch of flatwater for regrouping along the way.
In its early spring condition, expect class 3+ or 4 rapids; late spring
things calm down to moderate class 3, but there are several potential wraps
along the way.
The Moose
This is the Frankenstein of Adirondack Rivers, with rapids from class III
to VI-, depending on water level.
Before you go, get the latest info and seriously consider Hiring a Guide to accompany you. As with any whitewater trip, don't go alone. Share the fun with some friends or make new ones with the local foamsuckers (there are plenty).
