MANAGEMENT UNIT BOUNDARIES 



The Impact of the soda! and economic requirements of civilization 

 on the natural estuarine environment is the technical problem with 

 which management must deal, and effective control of this Impact can 

 be maintained only if both the major sources of damage and the 

 geographic range of their Influence are subject to unified control. 



Estuarine use conflicts and damages involve activities and effects 

 concerning both land and water. 



Many of the wastes which damage the estuarine environment originate 

 from cities, industries, and other activities on the land, and control 

 of the wastes from such sources is essential to effective management. 

 Shoreline development limits access to estuarine areas as well as modifying 

 some parts of the estuarine environment. 



An estuarine management unit, therefore, should consist not only of 

 the estuarine waters, bottoms, and associated marshlands; but it should 

 also include all of the shoreline surrounding the estuarine waters 

 themselves and as much of the adjoining land as is necessary to regulate 

 the discharge of wastes into estuarine waters. 



Effective control of water quality is one key to effective technical 

 management, and one essential requirement in accomplishing this is the
