The visual gauge is painted on the gorge wall (also known as Cabin gorge) in the Lower Section; you have to stop along the Kancamagus to look at it. It is located about 1 mile below the Albany covered bridge. Look for cabins across the river as the river drops below the view from the road; park carefully along the narrow shoulder and look up against the cliff on river left.
3/4' .....minimum scratchy level
1.25......Low
1.75......Low to medium
2.25......Medium
2.75......High
3' .......very high
In the summer of 2009 a new USGS gage was installed on the river right bank just downstream of the visual gage. We are still in the process of correlating this new gage.

Estimated chance (%) of finding the river runnable.
Month............% chance.................comment
January ............. 0%....frozen. February..............0%....frozen. March.................5%....Usually frozen. April................65%....Best chance mid to late April May .................35%....Best chance in early May. June.................10% July..................3% August................3%....Just a trickle September.............8%....Tropical storms and their remains October..............15% November.............30%....Fall rains, dormant trees December.............20%....River starts freezing early to mid month.
Be aware this is averaged out over several years. The % chance refers to the probability of finding the river running on any given day. For instance a 3% probability for August means on average you can only expect 1 day of water. One year there could be 2 days in August with water, other years none. Spring levels are usually higher than fall levels. The river rises and falls rapidly because of the small steep watershed. An occasional summer storm could bring the river up for a day.

painted... seems like it has changed. Currently a foot "feels" like a foot and a half. We suspect
that the level - at least in terms of the boater gauge appears lower than it really is within a few
inches and so far - at the lower end of the boatable levels (1-2')
Darby Field sign. Although there are some differences, most are subtle and are minor changes to
lines. Upstream of the cabin gorge, there used to be a log with a small US flag on it. The log is
gone but it is a good historical reference to the following: The river did a large S-turn into the
eddy just above cabin gorge. After Irene, at a little over a foot on the paddler gauge- there is a
new slightly bumpy line down the right side of this, at higher level it goes pretty smoothly. Gorge
is the same. Curious to hear what people think about things, I think one of the really big rocks
moved a bit to the left, the big one just upstream of the gauge in the middle that the typical line
went around either side. It felt tighter on river left along the wall... We ran the typical line
down the center and left of center in the staircase. The bottom has shifted a little but the line
still goes. Center seems like it has a slightly wider tongue at the very bottom. The steep reach,
just above house rock which is just upstream from some wide ledge holes, and a takeout/swimming
hole ledge is a little different. There has always been a hole on river right, then a dark colored
rock in the middle. There is a new rock now to the left as well. So two tongues - between the hole
and the dark rock or the two rocks. The debris on the sides is amazing, how high and how much.
Where Hobbs brook comes in, there is a little pull off where we put in, there are huge piles. No
wood of consequence, but if we get another round of high water, and the debris piles start breaking
up, it could get ugly. From Darby Field down - about a mile or so downstream - past the class II
rapid, the river widened and filled in with cobblestones, it gets braided and shallow in spots,
loads of wood, but it is passable. It will continue to evolve with higher flows, including some
movement in the downed trees and wood piles along the sides.
damage throughout the region, the worst in over 100 years. More than half the rivers in Vermont and
northern New Hampshire recorded their highest flow levels ever. Many roads, guardrails, power
lines, bridges, trees and other debris now litter several rivers throughout the region. River beds
have been scoured and changed course, many new strainers make navigation problematic at best and
downright dangerous at worse. Please realize that the river description you see here may not match
current situation after the floods. Use common sense and when in doubt scout especially on blind
drops. Also, if you run this river in the next year or so please comment on its navigability, even
if there are no problems this will be very helpful. Please report any new strainers or changes to
the rapids that will impact future boating. Thank you,
