A developed boat ramp has been constructed on the west side of Round Lake where highway 9 comes close to the lake. There are lots of parking spots. Adds about 3 to 3.5 miles of scenic flat water (and lots of tree falls to scramble over/around). Watch for the bald eagles nesting along the southern edge of the lake.
There are a few parking spots in a gravel area next to the train tracks. If you can easily fit under the bridge, the flow is low. If you have to lean back to fit, the water is medium. If you don't fit under the bridge, the water is high.
After the put-in will be 1.5 miles of twisty flatwater, riffles, and rock dodging. There are often downed trees and strainers.
The opening of this run is fairly mild, but there is a small rock garden section which can be a nice warmup.
This old arched bridge signals the beginning of the Roundhouse Rapids section. The creek will begin to pick up as you come around a bend up ahead.
You will paddle through some choppy water around bend and under power lines. You will see a small island ahead that has two paths around it. The first you notice continues off at about 45 degrees to the left. The 2nd path, a 90 degree turn to river right, will come into view when you are almost on top of it. Go Right! At first you might not even see the right-hand channel, but that is where the main flow is. The left channel is sometimes runnable, but it is very shallow and usually choked with wood that you can't see from above. Unless you have scouted left and have high flows, Go Right.
This rapid can be tricky. The current will try to push you into the island in front of you and the main drop happens as you are executing a 90 degree turn to river right. Most people "cut the corner" to avoid turning perpedicular to the creek flow. Immediately after taking your hard right, you must take a hard left over a smaller drop. You will then pass through some choppy class II water down to where the left channel joins back into the main creek flow. The rapid ends as you come within site of route 67.
After a mile of mostly flat water you will pass an old powerpole that is sinking into the creek. This is the halfway point between Roundhouse and The Apartments. The water will begin to pick up from here and become a steady class I-II as you enter Mechanicville.
You will pass under Vial Ave Bridge (arched bridge with a chain link fence on top). This marks the start of a long section of class II water know as The Apartments. You'll come around a left-hand turn, under a pedestrian bridge, then around a right-hand bend after which the water becomes calmer.
This section changed significantly between 2015 and 2017 when Mechanicville's downtown area underwent reconstruction. Much of this stretch used to be inside a tunnel, but is now open to the sky and easily scoutable from Main Street.
The Downtown rapids is a long run of class II+ water through the heart of Mechanicville. The difficulty varies widely depending on water level. The creek is surrounded by concrete walls which amplify waves and put them at odd angles. As a result, this section can be class I+ at low levels, up to class III and probably the biggest water of the course at higher flows.
You will come into a section of choppy water and wave trains at the start of Downtown. Because of the sheer walls and lack of boulders there are few, if any, places to stop.
A short way in you will see a large concrete wall directly ahead, and the creek will make a 90 degree turn to the right. After this turn will be a number of smaller bends, and one river-wide ledge that can form an impressive hole at most levels. The downtown section ends when you pass under the N. Main St bridge. A very large wave will form directly underneath this bridge when the water is high. If you go out of your boat here be prepared to swim all the way to the Hudson.
The public mooring area is on river left of the Tenandeho at its confluence with the Hudson. There is public parking.
There is no online gauge for this river but the online gauge for Glowegee Creek can give a good estimate of when Tenandeho is runnable. At Coons Crossing you can tell if the water is low, medium or high by how easily you fit under the bridge. You can easily paddle under the bridge when the water is low and probably class I or II-. If you have to duck significantly then the flow is medium and a solid II. If you have to press to the deck or can't really fit underneath it and need to launch on the downstream side, the flow is high and class III.
Runnable level: The Tenandeho typically has boatable flows in spring during snowmelt, or for a short time after a heavy rain. The creek does not hold water for long.
Permits are not required for this reach.
Take route 87 (aka: The Northway) to exit 11, then turn East following signs for routes 9 and 67. At the traffic circle, take the 3rd exit following signs for route 67.
You will come to a 2nd traffic circle. For the alternative put-in, take the first exit off the circle onto Route 9 South, and stay on 9 all the way to the DEC launch on Round Lake.
For the take-out or main put-in, take the 2nd exit (straight across) following signs for route 67 East. Continue on 67 East to Coons Crossing for the put-in, or to N. Main Street for the take-out. Turn right in both cases.
