Abstract

The work on Swan Lake was continued as in the previous four summers. The information obtained gave us some pretty clear indications of the changes taking place in the lake as a result of the effluent from the Colter Bay area. For some of these determinations you are referred to the summary in the 1957 Annual Report. Sufficient data is available now to justify a compilation of work up to this point for publication. Since this should be completed and ready for publication in the near future, there will be no attempt to summarize the data in this report. Project Number 75.
