Description of the (Devonian) rocks 

 underlying eastern Lake Erie, of the 

 shore topography, and the bottom de- 

 posits (principally mud and clay but with 

 considerable stretches of sand, and 

 some rock outcrop).

Studies of records accumulated by 

 municipal and industrial users of Lake 

 Erie water suggest usefulness of the 

 data for understanding of past changes 

 in the Lake and monitoring to detect 

 new ones. Informational gaps that should 

 be filled to permit more effective use of 

 records are listed. Work performed 

 under contract between Bureau of Conn- 

 mercial Fisheries and The University 

 of Michigan.

Record of chemical analyses of water 

 of eastern Lake Erie for dissolved 

 oxygen, various forms of nitrogen, pH, 

 C02, and carbonates. No evidence of 

 harmful pollution appeared at any station 

 in the open Lake.

Despite enormous variability of 

 samples taken by meter nets it is clear 

 that the bulk of the macroplankton is 

 made up of eight copepods, seven 

 cladocerans, one mysidacean, and a few 

 insect larvae. Cladocerans are most 

 important as fish food; Daphnia pulex 

 alone averages more than half the total. 

 Maps show local differences and sea- 

 sonal changes in the plankton. Brief 

 summaries are given of the distribution, 

 abundance, and ecology of different spe- 

 cies.

Results of bacteriological examina-

 lution was not a factor in the abundance 

 of fish.
