Therefore, water needs of fish and wildlife outside the defined service area of the Pacific Southwest Water Plan are not included in this Appendix although some discussions of fish and wildlife facilities which may be needed in connection with the North Coast Storage and Conveyance proposals are presented. Some of the potential fish and wildlife enhancement facilities along the proposed conveyance route may properly be assigned, all or in part, to some segment of the Central Valley Project or the California's State Water Plan. Decision on this assignment can, of course, be made only following appropriate study and review. Water supplies for Federal and state wildlife management areas, both existing and those that may be proposed, will be of particular concern in the future studies and planning activities. Supplies for fish hatcheries that may be proposed for enhancement or for restoration of salmon in the San Joaquin Valley apparently are more properly related to the East Side Division of the Central Valley Project. Similarly, flows in those streams for restoration of natural spawning areas, artificial spawning channels or for transportation of these fish to and from the sea, might also relate to that project. Fish hatcheries to mitigate the effects on anadromous fish will be required in relation to Helena Dam of the Trinity River Project and to Eltapom Dam of the South Fork Trinity River Project if these projects are authorized and constructed. These installations would require constant supplies of at least 70 and 80 second-feet, respectively. If the hatcheries are constructed as anticipated at sites immediately downstream from the dams, these supplies would also contribute to the water needed to maintain streamflow in the affected streams in support of fish maintenance, fishing, and other downstream uses. Streamflow maintenance and other aspects of fish and wildlife mitigation of these Trinity River projects are fully treated in Chapter II of the underlying report in the discussion of projects requiring further study before authorization. A constant water supply of 75 second-feet is required for the existing fish hatchery on the Trinity River near Lewiston. This constitutes a valid existing nonconsumptive use of water. This hatchery was built at Federal expense to mitigate the effects of the Trinity River Division, Central Valley Project on anadromous fish resources. It is now operated by the California Department of Fish and Game under contract with the Bureau of Reclamation. Under the Pacific Southwest Water Plan, it is proposed to be operated as a unit of the National system of fish hatcheries to supply trout to the proposed north coast storage reservoirs and others in the vicinity. Water needs are non defined here for other anadromous fish hatcheries that may be required, if other storage features are built as part of the Pacific Southwest Water Plan on the Eel River or elsewhere. Definition of these needs must await more complete formulation of engineering and related fishery plans. 18Epson Perfection 4870 Photo, 400 dpi, 8 bit, 14,010,368 byte
