The regulation of the Colorado River has had both positive and negative effects on aquatic resources. Controlled cool water releases from dams have provided for increased productivity of some aquatic resources and the development of significant introduced sport fisheries. However, the same releases may be detrimental to endangered and other native species of fish. Consultations with the Fish and Wildlife Service in compliance with Section 7 of the ESA on the operation of the Aspinall Unit on the Gunnison River, Navajo Dam on the San Juan River, and Flaming Gorge on the Green River will continue in 1999. Studies associated with these consultations will be used to better understand the flow related needs of endangered and other native species of fish. Modifications to planned operations may be made based on changes in forecast conditions. However, due to the recovery program for endangered fish species in the Upper Colorado River Basi~i, Section 7 consultations, and other downstream concerns, modification to the monthly operation plans may be based on other factors in addition to changes in streamflow forecasts. Decisions on spring peak releases and downstream habitat target flows may be made midway through the runoff season. Reclamation and the Fish and Wildlife Service will initiate meetings with interested parties, including representatives of the Basin states, to facilitate the decisions necessary to finalize site-specific operations plans. All operations will be undertaken subject to the primary water storage and delivery requirements established by "The Law of the River" and other applicable statutes, including water quality control, recreation, enhancement of fish and wildlife and other environmental factors. 58
