There is also concern that a take-out in the immediate vicinity of the fish passageway could disturb fish entering the river; but, according to the Service, this concern only exists within a reach less than 100 feet from the passageway. In summary, the Redlands Diversion Dam would remain a very real safety hazard to boaters; but the fish passageway proposal would not aggravate the situation nor would it preclude future options for safe river use. Trespass cited previously will not be affected unless enforcement activities are increased. The appearance of the area will change substantially as gravel mining operations by others begin upstream under all alternatives. Fencing of the immediate area of the passageway will reduce use of the dangerous area immediately downstream from the Redlands Diversion. This will also direct boat portagers who may be trespassing to put their boats in downstream at a safer distance from the dam's currents (approximately 50 feet further downstream). The fish passageway and associated fencing will be another human development introduced into the visual landscape. It is located in the immediate vicinity of a pumping plant and the diversion dam so the new structure will be compatible with existing uses, but it will be noticeable. Revegetation efforts will help reduce any visual impacts, and the presence of more people working in the area will hopefully reduce vandalism and trash dumping. Additional river flows in the 2.3 mile reach downstream from the diversion in dry periods will be beneficial from an aesthetic standpoint. Summary and Environmental Commitments In summary, the primary effects of the proposed actions under Alternative A will be to allow native fish to move into habitat that has been blocked for almost 80 years. River flows downstream from the Redlands Diversion Dam will be improved in low water periods to the benefit of aesthetics, fish and wildlife, and recreation. The proposed actions are expected to have a beneficial effect on the Colorado squawfish and the razorback sucker. Water rights will not be affected, but water supplies could be affected in very dry years. The Aspinall Unit has provided water supplies through normal operating releases to water users in western Colorado for nearly 30 years-these benefits would continue through operational considerations under Alternative A, lesser so under Alternative B, and would be reduced under Alternative C. On a long-term basis, no significant losses in annual hydropower production and associated revenues are anticipated due to proposed changes in release patterns of the interim agreement. The following environmental and social/economic commitments are included in the proposals: • Minor wetland losses that occur will be replaced through special plantings in the vicinity of the impacts. 37
