The Deerfield River Watershed Chapter of Trout Unlimited (DRWTU) is conducting a survey of the spawning activity of wild brown trout on the river. Over the past several years redds (trout spawning beds) have been observed in the fall by a number of guides and anglers, but have yet to be formally documented. According to fisheries biologists and hydro electric dam operators, any trout smaller than stocked sizes (5” to 10” or so) caught by anglers on the Deerfield were exclusively the result of fish spawning in the tributaries of the Deerfield and migrating to the main stem. A classic conundrum.
The DRWTU is committing dollars and man-hours to resolve this question. The spawning survey will document and mark the location of individual redds; document the presence of eggs in those redds; and follow-up on the viability of egg-bearing redds in the Spring. DRWTU anticipates the survey will contribute valuable information to the discussion of native brown trout spawning in the Deerfield mainstem. With this information it may be possible to persuade dam operators to modify their releases to enhance the viability of trout spawn and ultimately create a robust native brown trout population.
Survey teams were trained by TU member and professional ecologist Mike Cole. Teams of TU chapter volunteers began locating and mapping redds the week of 11/13/17 in four study areas. Active redds will be revisited and evaluated for success in Spring 2018.
You can help by making a tax deductible donation to the chapter for this effort and/or encouraging your friends and relatives to donate. Please avoid disturbing the fish on the redds when you are fishing the Deerfield. If you have photos of wild browns (Brown Trout under 10” especially), please pass them along to the chapter by emailing to email@example.com.
