This report deals with the results of survey work completed by the Biology Branch of the Commission in 1964 and 1965. Information is provided on the distribution of macroscopic animal life in the sediments of the bay and adjacent lake. Samples of the sediments and water were collected for chemical analyses, in order to relate the distribution of animal types to the chemistry of the supporting environment. Particle-size analyses was carried out on the sediments because it was felt that the texture of sediments would affect animal distribution and indicate subsurface currents.
