River Description

The First Descent was recorded in Spring 2014 by Joey Tamarro and Brooke Sofferman
Description by Joey Tammaro

Here’s a video of the river:

Locke brook is a creek in ashby mass. it is a tributary of the Squannacook river so you know its tiny.This micro creek flows into the Squannacook river draining higher lands to the north in mason NH. This creek is located about 30 miles from nashua NH Lowell MA and Worcster MA so it is fairly accessable.

The Pines camp ground in ashby is the location of the put-in. The camp owners are very nice and dont mind kayakers we are trying to keep them as happy as possible they have been wonderful land owners thus far. Be sure to stop in and say hey to Doug at the Campground office before you unload gear in their parking lot. They have bathrooms, showers and water available if you're nice and willing to toss them a few bucks.
This creek is very flashy and takes heavey rains of more then an inch to bring this into a runnable level.
This run is about 2 miles long and drops a total of 323 feet over its entire lenth at low level it is bashy at high level its a great run very continous -IV/ IV nature

The area bellow the first rapid is is a huge log jam that creates this large pool but also breaks into many small streams get out and walk 25 yards around the mess put in right about next large drop and horizon line. Pine Campground wants this jam kept to create a swimming hole in the summer. Please leave the chainsaws at home.

After the main rapids listed, the river is mostly II/III to the takeout.

The second rapid (Crushinator) is a large drop about 25 to 30 feet in total by the time you get to the end of it. It starts out with a horrizon line that splits around a big tree and pile of rocks. The right side is pretty straight-forward paddle to the lip, slow, pick your angle head down an 8 foot slide and be ready for your run out into a manky class III+. The left line IV starts off the same but with right angle the bottom of the slide piles into large boulders and makes a nice pillow with exiting current rushing back right to center of river. Slide down left side off the small flake landing on the pilling conituing right into a manky run out -IV.

Slide Into The Danger Zone

Class - IV Mile - 0.7

After this point the river heads around a corner to "Slide into the danger zone" a short fast slide with a decent hole at the bottom at higher flows. Keep an eye out for another portage before the second half of the river. Through this, the river continues as a III+ with occasional let up until you reach the next set of rapids which are near two neglected homes.

Rapid Thumbnail Missing

Crack house (and or Cabin Rapid / Old Timey House Rapid / Delapidated) is a set of ledges the river washes down best is to follow the flow by starting on river left and working right tword the center. The eddy on river left though small is usually is very strong and gathers wood. Watch out you don't get eddied into the logs.

Back Alley

Class - IV Mile - 1.25
Rapid Thumbnail Missing

The next rapid is just down river Other house (Back Alley/Whore House/ Exit Drop/ Locked House) and is very similar to the other drops. Drops over several small ledges to a big pool at the bottom. Run up the middle but watch out river left has a rock pile and tend to gether wood

Run out Mile

Class - III Mile - 2
Rapid Thumbnail Missing

After this the river is mostly II/III all the way to the take out at the first bridge. Watch for logs and strainers, they are likely plentiful. 


Gage Descriptions

Start driving when it's 150 and rising. 250 cfs on the gauge correlates with a rain event that provided enough water for a low water run on Locke Brook. Correlation gauge is still being refined.

Whitewater boaters from Maine to Pennsylvania gather each June in Charlemont, MA to celebrate whitewater boating and American Whitewater's river advocacy to protect, restore, and enjoy our northeast rivers. While we can't gather in-person this year, we'll be having a virtual Deerfield Fest Membership Event this Friday, June 26th at 7 pm (EST) . We'll be giving away some fun AW merchandise and other prizes for those who JOIN or RENEW their AW Membership and join us on Friday, so REGISTER for the virtual Deerfield River Membership Event today and join us for this fun event in support of AW.

Deerfield River (MA) Flow Studies to Explore New & Improved Boating Opportunity

Robert Nasdor

In response to requests by American Whitewater, several affiliates, and other stakeholders, FERC directed Brookfield Renewable to study the impact of its hydropower operations on whitewater boating on the Deerfield River in western Massachusetts. Boating groups and our supporters are seeking to determine optimal whitewater boating flows from the Fife Brook Dam and whether changes in hydropower operations would enhance boating opportunities, access and navigation.

AW Responds To Connecticut River Boating Study (MA)

Robert Nasdor

American Whitewater, along with other paddling groups and outfitters, filed comments with FERC responding to the Whitewater Boating Evaluation at Turners Falls on the Connecticut River. The study showed that there is strong demand for boating on this section of the Connecticut River if sufficient flows, scheduled releases, better access, and real-time information are provided. The groups filed the comments in order to provide additional information for the environmental review and to respond to the unsupported statements by FirstLight, the utility performing the study, claiming that there is little demand for boating at Turners Falls.

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.
