EFFECTS OF POWER-PLANT OPERATION 615 



The phytoplankton community of Belews Lake appears to be 

 proceeding through a series of long-term successional changes in 

 response to the adjusting and equilibrating environment of this new 

 impoundment and to local climatic changes. Power-plant operation 

 has superimposed a greater homogeneity on the phytoplankton 

 community and has not appeared to cause any detrimental effects 

 within the period of this investigation.
