There is a gauge located in another branch of this system which could be used for correlation. However, there is no 75th percentile or paddler observations to base any correlation off of. If you run this section please check the online gauge and leave a comment with the flow and a description of the run.

USGS discontinued the gauge, now it is operated by NHDES:

The log is no longer there. From under the bridge, looking down, it will look like there is a log spanning the right side of the river (and that you'd have to make the move to the left) but that isn't the case. The whole run is good to go, a couple logs sticking up here and there but nothing very significant.

There's a log spanning the river near the bottom of the run that you can't see from the bridge - you can sneak around it by catching a river left eddy, but make sure you can catch the eddy before putting on

Gage Descriptions

Jolyon Rivoir-Pruszinski provided the following information

The downtown section of the Mascoma comes into a runnable range every year with the drawdown (almost regardless of the starting level of Mascoma lake). Last year for instance it ran at about 200 cfs for about two weeks despite a very low level on lake mascoma during the summer. The upper (easier) section takes more water for a good run (usually 250 cfs min).

I usually will paddle downtown down to about 120 cfs. At these low levels it is pretty bony but definitely fun (class 4 or so in difficulty of moves) and easy to break down into sections by competent class 4 paddlers. The hazards are a little more significant than one would encounter on a typical class 4 run (rebar / pinning etc) but if you know where to go you can still make a very clean run. Obviously it's better with more water, but much more intimidating/ difficult than at low water. Around 300 cfs it starts to feel less bony and at around 500 cfs it starts to feel much more pushy. Above 500 it would consider it class 5 mainly for the hazards and the continuous nature. Swimming, unfortunately, is almost always met with injury on this run.

Protecting Access to New Hampshire Rivers

Robert Nasdor

Northeast boaters can celebrate that another beloved whitewater gem has been protected. Paddlers on the Winnipeseaukee River are now assured that the put-in on the Lower Winni in Northfield, NH will be forever protected thanks to the donation of a parcel from Gloria Blais in memory of her husband Roger. Gloria donated the land to the Town of Northfield for the purpose of assuring that future generations of boaters will have access to the river. Protecting river access to the Winni is part of an ongoing effort by AW in the northeast region to protect river access.

Bellows Falls (VT) Flow Study Reveals Hidden Whitewater

Robert Nasdor

A hardy group of northeast boaters climbed into the natural river channel below a hydropower dam to participate in a flow study designed to assess whether whitewater flows should be restored to this dewatered river reach on the Connecticut River. While significant obstacles remain, this site has the potential for providing instruction, playboating, and a big water feature that that could be run throughout much of the year and provide a much needed boost to the local economy.

AW, MVP Protect Land and Access on the Contoocook River (NH)

Robert Nasdor

American Whitewater and Merrimack Valley Paddlers have reached an agreement to purchase a 10-acre parcel fronting on Contoocook River in Henniker, NH. The land serves as an important launch point for whitewater paddlers enjoying the popular section of the river that runs from Hillsborough to Henniker. This section of the Contoocook River contains rapids ranging in difficulty from Class II to Class IV.
