is organized into 14 "Handbook of Descriptors" sections. A brief de- 

 scription of each of these sections and the types of information they 

 are designed to contain follows : 



Section 1 identifies each estuarine subdivision according to its type, 

 location in the United States, including States, counties, congressional 

 districts, and the systems to which it is tributary. 



Section 2 describes the physical structure of each estuarine sub- 

 division ; including its size, shape, total water area, area of marshland, 

 climate, and any artificial circulation-modifying structures in the 

 system. 



Section 3 gives those areas which are owned by various political 

 subdivisions, or which are zoned and under the control of special dis- 

 tricts or management compacts; areas of parks and other recreation 

 areas ; and a list of the management compacts with particular interest 

 in the estuarine zone. 



Section 4 describes the hydrology of the estuarine system, including 

 data on river flow and identification of major flow regulation 

 structures. 



Section 5 includes economic statistics on population, extent of 

 urbanization, industrialization, commercial buildup, employment, etc. 



Section 6 describes the oceanography of the area, including tidal 

 regime, current patterns, and tidal prism. 



Section 7 includes water quality information, listing extremes and 

 variations and pertinent typical values in many water quality 

 parameters. 



Section 8 includes information on sedimentation and bottom charac- 

 teristics of the area. 



Section 9 describes the uses to which the area is put. 



Section 10 describes sources of wastes, both municipal and industrial. 

 It also includes a summary of the total amounts of waste and an in- 

 dividual listing of major waste discharges. 



Section 11 includes statistics on use damages, both in terms of 

 quantity of use lost and amount of monetary damage. 



Section 12 included a list of immediate pollution abatement needs. 

 FWPCA is now in process of developing a system of records main- 

 tenance on these needs and progress in meeting them so this section 

 has been deleted from the inventory until a later date. 



Section 13 includes the water quality standards as presently approved 

 for each State, and the acreages reserved for various beneficial uses 

 as required by the standards. 



Section 14 presents a list of past and current studies in the system 

 identified by date, type of study, and the person or organization 

 responsible.
