In 2012, the Bonneville Power Administration (BPA) prepared an environmental impact statement to analyze the effects of the construction and operation of the Mid-Columbia Coho Restoration Program. This program is implemented by the Confederated Tribes and Bands of the Yakama Nation and funded, in part, by BPA. The goal of this program is to restore a naturally produced, self-sustaining population of coho by releasing up to 1.16 million coho smolts in the Wenatchee basin and 1.0 million coho smolts in the Methow basin annually. The action proposed in the EIS included a small new hatchery in the Wenatchee basin and 24 acclimation ponds in targeted tributaries in the two basins. The action also included the collection of adult coho to artificially produce coho eggs and juveniles at various hatcheries in Washington and Oregon.
Since the EIS was completed, the Yakama Nation has conducted work at three acclimation ponds. In addition, they found that some modifications to original proposals are required. BPA has prepared a number of supplement analyses (SAs) to evaluate the environmental impacts that may occur as a result of these changes.
BPA is currently analyzing the potential impacts of three acclimation site replacements and a location adjustment for the Natapoc hatchery.
SA-03 - Merry Canyon and Trinity Acclimation Ponds: BPA initiated scoping for these two replacement acclimation sites on August 1, 2014, and accepted comments from the public until September 9, 2014. Comments are found below. We anticipate that the SA will be available to the public in early 2016.
SA-04 - Natapoc Hatchery: BPA initiated scoping for this new hatchery on November 4, 2014 and accepted comments until November 19, 2014. Comments are found below. The program EIS addressed this hatchery under its former name, ?George,? but the proposed hatchery was later re-sited in order to avoid wetlands and wetland buffers, and to provide a higher level of effluent treatment than was originally proposed. We anticipate that the SA will be available to the public in early 2016.
SA-06 - Early Winters 3 Acclimation Ponds: BPA is initiating scoping for a coho acclimation site near Early Winters Creek in Okanogan County, Washington. This site is a replacement for sites that were addressed in the EIS, but later became unavailable. We anticipate that the SA will be available to the public in early 2016.
