Scott: Lakes of Tippecanoe Basin

APPENDIX C: DISTRIBUTION OF PLANKTON 



The following tables exhibit the distribution of the most 

 significant plankton. The Crustacea are excluded inasmuch as 

 their distribution seems to present a special problem. The depth 

 in meters is expressed in the first line. In part of the lakes, 

 disintegrating Microcystis has been marked d. (dead). The 

 colonies that were evidently alive were marked 1.
