Update: Phase 3/Twin Rivers Extension Project Work Complete - 2008
|
Work on the third phase of the Twin Rivers Farm Habitat Restoration poroject was completed in early September.
During this phase of the project, an additional half-mile stretch of river was restored with the installation
of large woody debris and slate structures similar to those installed downstream in the first and second
phases completed in 2006-2007. Details on this year's work forthcoming. For more details, see the
Batten Kill Watershed Alliance website.

Planning Under Way for Phase 3 - 2008
|
|
Plans are on the drawing board and the necessary permits and contracts are being secured and drawn
up for the next phase of habitat restoration work in the Twin Rivers Farm Project. Building on the
success and experiences gained in the earlier phases of the project, work on the next phase of the
project is scheduled to begin in late summer/early fall of 2008. Work will begin in the reach of
river upstream of the already restored sections. For more information, refer to the
Batten Kill Watershed Alliance website.
Additional details will be posted as they become available.

Update on Phase 2 - 2007 -- Completed!
|
|
Work on Phase 2 was completed on Wednesday, September 19, 2007, with the anchoring of the last cover
trees, seeding, mulching, and rehab of the upper landing and island (areas used by the crew for
materials staging and for access the river for the purpose of the project.) According to Scott
Wixsom, Biological Technician with the Green Mountain National Forest, "the project turned out very
well, weather and water levels cooperated, no injuries sustained nor breakdown of equipment."
Special Recognition and Thanks
Aside from the multiple partner organizations involved, much support was received from many people
before and during the project, but one group that stands out and often receives little recognition
is the corps of various contractors who played a key role in making incredible things happen on the
ground and in the water: including Dean and Noel from Dydo, Pat and Shawn Salo, Joe Nolan and Nate,
Steve Morse, and Keith Squires. All very professional, dedicated, and hard working individuals.
A HUGE thank you for a job well done!

Installation of the Phase 2 cover and shelter structures begins Monday, Sept 10, 2007. See below
for diagrams of the planned cover and shelter structures. These structures will consist primarily of
root wads and tree trunks, but will also incorporate existing trees and large boulders. Stay tuned
as we'll post photos of the installed structures in the near future.
|
|
The project partners have been hard at work over the winter, individually, and collectively. Two planning
meetings for Phase 2 and beyond have been held to date - including one in Dec 2006 and another in
March 2007. Tentative site design plans for Phase 2 are presented below. Please note, however, that
these plans are tentative and have NOT yet been finalized or received final approval. Much depends
on how the spring runoff affects the existing structures installed just upstream, in Phase 1.
(See below for photos & diagrams from Phase 1.)

Below are two sets of drawings of the stretch of river that will be worked on in Phase 2. The first
set represents the existing conditions prior to the beginning of the project. And the second set of
drawings are a *preliminary* view of the planned in-stream structures that may be installed in Phase
2.

Update on Phase 1 (completed 2006)
|
According to Steve Roy, Fisheries Program Manager for the Finger Lakes/Green Mountain National
Forests, as of January 3, 2007:
"The habitat work at the Twin Rivers site is doing its job of
creating excellent cover and refuge for trout. The structures have
withstood several high water events including one bankful (channel forming)
event. The channel is changing as expected by forming depositional areas
near the banks and scour holes around the structures."
|
|
Work on Phase 1 has been completed.
|
|
Work on Phase 1 of the project began as scheduled on Monday, September 11 and
wrapped up early on Friday, September 15, 2006. See below for images and video
from the project site. More than 25 stream-bank an in-stream installations were
placed. Most of the installations were created using a combination of large
woody debris (root wads, large diameter tree trunks, and rock), were secured to
the stream bank and existing trees using chain, re-bar and boulders. The
stations were designed and laid out in such a way as to appear natural and as
'non-engineered' as possible. Several large slab rock structures were also placed
mid-stream to provide additional cover from overhead predators. The images below
show a sampling of the stream structures installed. Stay tuned for additional
details regarding the plans for Phase 2 of the project, scheduled for
implementation in 2007.
