Telemetry Study Update

Despite Covid 19, our Trout Telemetry study continues through the efforts of one of our newest board members, Kevin Kaminsky. Kevin has been making 2-4 trips up and down the river every week to ensure that our data is uninterrupted. If you’d like to check on up-to-date information about the movements of our 29 tagged brown trout, click here. We are hoping to get our cadre of volunteers back on task soon. Watch this space for more info.

Data plotted on a map of the upper C&R section based upon a trial run of the mobile telemetry receiver, reveals the location of 30 brown trout with newly implanted transmitters.

Catch a Radio Tagged Brown?

Volunteers from TU, USGS, US Fisheries and Wildlife, and MA Fish and Wildlife tagging fish for the study.

If you are following DRWTU here or through local media, you know we are embarking on a two year-long study of thirty radio-tagged brown trout in the Deerfield River. This collaboration already involves scores of volunteers from TU and partner conservation agencies, biologists from the USGS Silvio Conte Anadromous Fish Lab, and MA Fish and Wildlife. What should you do if you catch one of those radio-tagged trout?

Please gently and quickly unhook and release the trout back into the Deerfield. Then when you get within cell phone coverage, please call and report the catch to DRWTU President Mike Vito at 413-320-1521. You are going to want to report the catch to MA Fish and Wildlife using the link on our banner above.

Tagged browns have a thin wire antenna trailing back from their abdomen.

What if you ‘take’ a tagged fish legally or find a dead fish with a radio tag? Well, we would hope you would forego taking a fish out of our study, but if you choose to take the fish we can reuse the transmitter. Please call 413-320-1521 to make arrangements to turn it in.

The antenna wire is just barely visible in the photo along the flank of this beautiful brown trout.

Where Do Brown Trout Go?

While Ted Castro-Santos fine tunes the telemetry receiver, Kris van Naerssen aims a YAGI antenna at a transmitter submerged just downstream of Fife Brook Dam by DRWTU President Mike Vito (out of sight). Board member Bill O’Bear looks on to understand the operation of the directional YAGI antenna.

Finding wary trout and learning their sometimes fussy habits go hand-in-hand with fly fishing, but this year the Deerfield River Watershed Chapter of Trout Unlimited (DRWTU) is going to take that notion to a whole other level. Rather than scouring the river with fly rods and nets, members and volunteers will use electronic equipment as part of the group’s most ambitious conservation project to date. 

​Our local TU Chapter is preparing to commence a brown trout radio telemetry study, which may be the first of its kind on any similar-sized river controlled by hydro-electric dams in the United States. The study is designed to investigate the impacts of daily hydro-peaking flows on trout living in the stretch below Fife Brook Dam in Rowe.  Partnering with biologists from the USGS Silvio O. Conte Anadromous Fish Lab in Turners Falls and the Massachusetts Division of Fisheries & Wildlife, DRWTU is expanding its role as citizen scientists to identify the specific challenges to trout caused by the Deerfield River’s current hydro-peaking flows.

You can contribute to the study through donations of time and or money.

Biologist Ted Castro-Santos instructs DRWTU board members on the principles and operation of the telemetry equipment, with support from Jadziah Hanson-Moorstone, intern at the Conte lab and biologist from USFWS.
Biologist Ted Castro-Santos with the help of Matt O’Donnell secures one of DRWTU’s telemetry transmitters onto the anchor line of Chris Jackson’s raft.
DRWTU Board Member and River Guide Chris Jackson volunteered to row his raft in the August 15 trial of DRWTU’s newly acquired telemetry transmitters and receivers.
DRWTU Board Member Chris Jackson tows a radio telemetry transmitter attached to the anchor of his raft through rough water on the Deerfield River. Biologists from USGS safeguard the transmitter and record waypoint data while running a test of the DRWTU equipment. The equipment tested out perfectly, with better than expected reception via vehicle-mounted antenna from the road along the Deerfield.

Spawning Study Final Report

We are very excited to be able to share the final report of the Second Deerfield River Trout Spawning Study. The pdf is available to read or download here. The report authored by Erin Rodgers, PhD, with contributions from Mike Hayden, was submitted to TU National on July 13 as part of the final Embrace a Stream grant report. Thanks to the efforts of our members and the friends of DRWTU who participated in this study, we have been able to demonstrate that brown trout spawning on the mainstem of the Deerfield is not an anomaly. The Deerfield River is a wild trout fishery!
