Book Description
Willamette Basin is a major contributor to the economic well-being of the Pacific Northwest. Its agricultural and forest lands are the basis for products shipped to the nation and the world. Its people, and their industries, provide a market for products and raw materials from national and world-wide sources. As development in the basin continues, flood damages become greater and economically more devastating. The purposes of this appendix are to outline past and present flood problems in the basin, determine the present and future needs for flood damage reduction measures, and outline available flood damage reduction alternatives which should be considered in plan formulation. The scope of coverage includes flood characteristics, flood damages, enhancement of land values, existing projects, and damages prevented; and structural and management alternatives for prevention of flood damages. (Author).

Book Description
The Land Measures and Watershed Protection Appendix is dedicated to programs and measures that modify land and water resource use to avoid impairment of the environment and to repair physical damage already done. These general goals involve the prevention of excessive erosion, control of storm and sediment damages and improvement of quantity and quality of water runoff. The opportunity for increasing resource outputs on lands having problems of drainage, flooding, lack of irrigation water, or lack of adequate management systems receives attention for agriculture and forest lands. The primary purpose of the appendix is to identify measures and programs that insure the following: (1) The quality of the agriculture and forest environment will be maintained or enhanced by modifying present use to protect the long term resource capacity; (2) The resource base (soil, water, vegetation) is capable of producing today's required output; (3) The Willamette Basin is in a state of readiness that can respond to future agriculture and forestry productive demands that may be placed upon it; and (4) Developments, activities, and uses that do take place can coincide with positive opportunities of community development and improvement of man's total environment. The measurements of this appendix are unique due to the important element of stewardship. The soil-water-vegatative system is regarded primarily in terms of total environment--not merely as an agricultural or forestry protection or production matter. As land space becomes more valuable, the effort to safeguard its continued use becomes more difficult and costly.

Book Description
The purpose of this appendix is to appraise the present municipal and industrial water supply situation, to analyze its future needs and development potential, and to evaluate the needs of subareas as a basis for making recommendations for measures which will serve those needs. Consideration of municipal and industrial water supply as a part of a comprehensive plan for development and management of water and related land resources is essential to provide a means for orderly development of water supplies. The scope of this appendix limits projection of municipal and industrial water supply requirements to the years 1980, 2000, and 2020. Appraisal of the 1980 requirements includes consideration of quantity, quality, and seasonal variations of supply and demand. The need identified is of an immediate nature and may be directly related to the development of a comprehensive plan for readily foreseeable developments. The long-range plans, which are naturally more conjectural, are more general in nature and point toward the needs of major subareas of the basin. The study area is confined to the Willamette Basin; however, the strong geographical and economic interrelations and interactions between the Willamette Basin, the Pacific Northwest, and the Nation will influence the level of municipal and industrial water demand in the basin. As an example, increased market area population will result in an enlarged market for processed food. Additional food-processing capacity will result in an increased demand for process water and water for the additional population supported by the industrial employment.

Book Description
The Willamette Basin is one of the better watered regions of the United States. The average annual precipitation of 63 inches results in a volume of more than 40 million acre-feet of water falling on the basin annually. Of this amount, about 26 million acre-feet runs off in the principal streams that drain the area. Most of the precipitation and runoff occurs during a few months in the winter, and natural water supplies are deficient during the late summer and early fall. Because of the diverse terrain, both precipitation and runoff are distributed unevenly. For this reason, it has been necessary to construct facilities to store the surface water and to drill wells to tap the ground water. As the population and economy of the basin grow, many additional water developments will be needed. The purpose of the Willamette Basin Comprehensive Study is to develop information on future water and related resource needs and to prepare a plan for meeting those needs. This appendix contains a description of the water resources, their distribution, and their variation at different periods of time throughout the Willamette Basin. These resources are described in terms of the climatic, geologic, and other environmental factors that influence and control the occurrence of water. The appendix provides statistical and interpretive hydrologic data necessary for broad-scale water-resources planning. These data are essential to the development of plans for meeting the basin's water needs and solving its water problems. (Author).

Book Description
The purpose of this appendix is to examine the fish and wildlife aspects of the Willamette Basin, and develop recommendations which will adequately provide for preservation and improvement of these resources. Included in this appendix are sections on: background information with a brief history of fish and wildlife; inventory of present fish and wildlife resources; appraisal of future supply and demand; alternative means to meet the demand; and a final section with a summary and recommendations based on data in the preceding sections. This appendix is essentially single purpose in scope. The data presented are generally of a reconnaissance level to give a broad-scaled analysis of future requirements for development of fish and wildlife resources throughout the basin. More detailed data are presented in those instances where the need identified is more immediate and will require specific action within the initial development period.

Book Description
The purpose of this appendix is to appraise the present irrigation development, outline the irrigation potential, and present recommendations for the orderly and efficient development of irrigation within the basin. These findings are used in formulation studies to develop the overall comprehensive plan for water and related land resources in the basin. This appendix is essentially single-purpose in scope. Projections of irrigation development are given for the years 1980, 2000, and 2020. Single-purpose means to achieve irrigation objectives are also given. These analyses are made on the assumption that there will be ample water for full irrigation development. The data presented are generally of a reconnaissance level to give a broad-scaled analysis of future requirements for development of irrigation in the basin. More detailed data are presented in those instances where the need identified is of more immediate nature and will warrant specific action within the readily foreseeable future. (Author).
