Price-Stubb Fish Passage FONSI Page 5 be short-term in duration and not significant. Best management practices will be incorporated as • environmental commitments to minimize impacts to water quality including the use of • cofferdams and limiting in-river construction to periods of low river flow (November through March). Reclamation will request Clean Water Act Authorization from the Army Corp of Engineers for the discharge of dredge/fill (Section 404) to construct the fish passage. Permit conditions will be incorporated as environmental commitments. The selected alternative will have no adverse effects on wetlands or the 100-year floodplain. Disturbed areas will be revegetated to minimize erosion potential. River recreation will benefit from the proposed action by the construction of boater passage and the addition of whitewater features. The Downstream Rock Fish Passage with Whitewater Features will allow additional river recreation. Recreational benefits will be reduced under the Downstream Rock Fish Passage Alternative when compared to the recommended alternative if recreation funding is not obtained; however this alternative would still provide safe boat portage i around the Price-Stubb Diversion Dam. Public safety issues associated with the Price-Stubb Diversion will also be reduced under the selected alternative. The Downstream Rock Fish Passage Alternative will also reduce hazards • associated with the Price-Stubb Diversion Dam. During consultation with the Service (Consultation #ES/GJ-6-CO-03-F-016), the Service concurred with Reclamation's determination that the proposed project will have "no effect" on the bald eagle, southwestern willow flycatcher, and humpback chub. The Service concurred with Reclamation's conclusions that, overall, providing fish passage at the Price-Stubb Diversion Dam will benefit the endangered Colorado pikeminnow, razorback sucker, and bonytail. However, the Service determined that the proposed project may have some incidental adverse affects on Colorado pikeminnow, razorback sucker and bonytail and prepared • a biological opinion to comply with the Endangered Species Act. The biological opinion concluded that the proposed action is not likely to jeopardize the continued existence of the Colorado pikeminnow, razorback sucker, or bonytail nor destroy or adversely modify their • designated critical habitat. The Biological opinion stated: • "The Service anticipates that take of endangered fishes may occur when nonnative fishes have access to habitat between the Price-Stubb Dam and the Government Highline Dam (Grand Valley Project Diversion Dam). Take will occur when nonnative fish eat r endangered fishes and when nonnative fishes cause harm to endangered fishes by competing with them for food and space. Also, take could occur when Colorado • pikeminnow consume nonnative fishes with spines, such as channel catfish or black bullheads."
