In tables 23 and 24 are presented the results of temperature and chemical analyses
made on 15 affluents of Karluk Lake during the summers of 1935 and 1936. These
data, with the exception of the silica values, agree with the results presented for 1927
by Juday, Rich, Kemmerer, and Mann (1932). Variations in temperature, pH,
carbon dioxide, soluble phosphorus, and nitrite nitrogen depend, in a large degree,
on the time of day observations are made, the number of fish in the streams, and
depth of water in the streams.
