The framework plans and programs outlined in this appendix are presented as a compendium of measures which, after examination and critical discussion, have been thought by the study participants to contribute to a balanced use of water and related land resources. These measures were arrived at on the basis of the best information available. Although some details of the plan will become partly obsolete in a short time, its overall pattern will remain for many years an excellent guide to regional possibilities and opportunities.

The Economic Base and Projections Appendix is one of the five major components of the Columbia-North Pacific Framework Study. The purpose of this appendix is to provide basic inputs for the evaluation of present and future needs for water and related land resources and the formulation of framework plans for the management, use, and development of these resources. In addition, the report provides a basis for evaluation of the impacts of alternative resource developments on economic activity. The major elements of the study are as follows: (1) Inventory and analysis of economic activity and population in the study area, its linkage with related economic activity exogenous to the region, and analysis of significant relationships between economic activity and the quality and quantity of available natural resources, and (2) Projections of economic activity and population in the region based upon specific assumptions of national economic growth and the availability and quality of resources within and outside the geographic area of concern.

The purpose of this appendix is to assemble available water resources data in a summarized form to provide information, not only for the agencies dealing with the management of the water resources of the region, but also for those planning the economic development which is dependent upon those resources. Much information about the water resources of the Columbia-North Pacific Region is available but it differs widely in character, scope, and geographic coverage and must be obtained from many sources. Information also is available on various water laws, technological developments, and economic and population trends that will influence the availability of and requirements for water in the future. The goal of water conservation is the management of this renewable natural resource to provide the optimum benefits from use of the water, now and in the future. To achieve this goal, intelligent planning and orderly development are needed. Proper planning and development require adequate information about the water resource and how man's activities have affected and are likely to affect it.

The purpose of this appendix is to evaluate for the region as a whole and for each subregion the existing recreation resources and facilities, determine recreation needs, and outline framework plans to satisfy those needs in the foreseeable future for the water and related portion of outdoor recreation. Recreation values and needs are identified for the years 1970, 1980, 2000, and 2020. Major emphasis will be placed on the need for water-related outdoor recreation.

This Appendix I is intended to provide a broad history of the Columbia-North Pacific Region Comprehensive Framework Study. The first section, covering authorization, purpose, and scope, defines the study area and the level of detail obtained and outlines the broad objectives of the study. Following this is a listing and brief description of previous studies of a comprehensive nature covering major areas or basins within the region. The third section describes the organization established for conduct of the study and how it was funded and administered. Special attention is given to the coordination of the study necessitated by the numerous State and Federal agencies participating. All of the cooperating agencies are identified. The appendix concludes with a section describing some of the public information activities concerning the study which have been engaged in by the Pacific Northwest River Basins Commission and by study participants.

The purpose of Appendix X, Navigation, is to provide a broad picture of the important role water transportation has played in the economic development of the region, an inventory of existing waterway improvements and harbor facilities, projections of future needs and some general indication of measures that could be constructed to satisfy those needs. Measures to satisfy needs include all facets of navigation improvements required by commercial deep and shallow draft vessels and smaller fishing and recreational boats that ply the Pacific Ocean along the 500 miles of the region's coastal front, the 2,500 square miles of almost landlocked salt water comprising Puget Sound and adjacent waters, and the 2,880 miles of navigable rivers, lakes, and estuaries as defined by Act of Congress or court decisions or as designated by the U.S. Army Corps of Engineers.
