I. NASH STREAM, Stark/Odell, NH; Approx. 1.5 hrs drive time from Waterville (Morning)In 1969, an earthen dam ruptured, sending a wall of water and cobbled debris downstream which scoured and widened the streambed and embankments , destroying vegetation and instream habitat. Over the last century, the surrounding forest was logged and many poorly constructed and placed roadway culverts were installed, inadvertently closing off access for brook trout spawning to otherwise productive tributaries.
II. PEMIGEWASSETT RIVER, Exit 31 Route 93 North; 20 minutes north of Waterville; (Shore lunch will be provided here.)
During the construction of Interstate 93 many decades ago, this section of this premium cold water fishery suffered a great deal of damage. The instream channel was forced to divert, resulting in extreme bank erosion and destruction of refuges, pools and macro-invertebrate populations.
The Pemigewassett and Ammonoosuc Chapters of TU helped obtain $500,000 in grants for this reconstruction project. There will be a presentation after lunch that will show participants the details of the project.
