This paper deals primarily with the dangers to salmonid stocks, their 

 food supplies, shelter, and access to and from spawning grounds following drain- 

 age activities. Both beneficial and deleterious effects of drainage activities 

 are examined and compared with conditions obtained in natural waters. The 

 possibility of combining the desirable features of both systems with a view 

 toward conservation and improvement of stocks in artificial channels is 

 discussed. Suggestions are made and experiments described that would achieve 

 this result without interference, but possibly with benefit to other legiti- 

 mate uses of land and water. No conclusions were made pending results of 

 continuing studies.

This report includes a theoretical discussion of the reasons to suspect 

 dredging effects on zooplankton and a review of the available evidence to 

 make judgments on including zooplankton in future dredging research proposals. 

 It describes zooplankton biology that might be influenced by dredging and 

 reviews the literature that relates to these areas.

A survey of benthic mollusks in Boca Ciega Bay, Florida, showed a smaller 

 number and variety of species in the soft sediments in dredged canals than in 

 the predominantly sand and shell sediments in undredged areas. Samples con- 

 tained an average of 60.5 live mollusks and 3.8 species in undredged areas 

 and 1.1 individuals and 0.6 species in dredged canals. A list of mollusks 

 collected in this survey and in past studies included in an appendix.

Major environmental factors involved in planning coastal flood barrier 

 systems along the Texas coast are present in this paper. The intent is to 

 highlight important environmental aspects to be considered when planning a 

 protective system. This paper is not a treatise on the complexities of 

 design and construction of such a system. In this paper environmental aspects 

 are categorized: (a) ecological — man's habitat; (b) cultural — man's heritage; 

 and (c) esthetic — man's sensory perception of the environment.
