demands of the one will affect the other if present trends in develop- 

 ment continue without effective control by the institutional environ- 

 ment. The emphasis here is on technical management problems. 



Part V, "Development of the Comprehensive National Program," 

 discusses the institutional environment as it presently exists, shows the 

 role each level of government plays, and points out what role each 

 should play to achieve effective management. The emphasis here is on 

 institutional management problems in the estuarine zone. 



Part VI, "The Development of Data on the Estuarine Zone," dis- 

 cusses the present state of knowledge about all three of the major 

 estuarine environments, and presents a program of studies and re- 

 search efforts designed to close up knowledge gaps and provide the 

 basis for sound technical management through rational institutional 

 management. 



Part VII, "Collection of Supporting Information," describes in 

 general terms the mass of reference materials from which the informa- 

 tion in this report was derived. These materials consist of several 

 thousands of documents, including transcripts of estuarine public 

 meetings, profiles of Federal and State agencies, the study's contrac- 

 tors' reports, and published reports in the scientific literature which 

 relate to estuarine resources. 



In-text citations to published material, referenced in the following 

 volumes of this report, are indicated by a number in parentheses, 

 such as (V-1-1), which refers to the references list at the end of the 

 appropriate chapter. Likewise, figures and tables are referred to in 

 text by a number, such as figure V.1.1, or table V.1.1. Appendices fol- 

 low the appropriate chapter. 



In essence the report presents a technical analysis of the estuarine 

 zone, identification of scientific knowledge gaps, and an inventory 

 of the available knowledge, all of which form the basis for the recom- 

 mended comprehensive management program for the Nation's estua- 

 rine resources. 



This recommended national program is based on institutional man- 

 agement with multiple long-term use as a common denominator. For- 

 mation of the organizations to accomplish this and the active imple- 

 mentation of these recommendations will permit maximum use of the 

 entire estuarine zone while preserving it for the benefit of future 

 generations.
