The nature and abundance of O 2 and organic compounds were examined in the streams of the Marmot basin. Levels of dissolved O 2 in mountain streams of the Marmot basin averaged 11,000 µ g/liter. The streams were 90–105% saturated with dissolved O 2 . Biochemical and chemical demand averaged 2,000 and 4,000 µ g/liter, respectively. Total organic C in mountain streams averaged 4,000 µ g/liter. Analyzed organic compounds in stream waters constituted 25% of the total organic C, refractory compounds accounted for 23%, and labile compounds 2%. Refractory organic compounds, humic and fulvic acids, averaged 790 µ g/liter and tannins and lignins 100 µ g/liter. Averages of labile compounds were: hydrocarbons, 0.05 µ /liter (sum of individual compounds in the range of C 14 –C 32 ); phenols, 2 µ g/liter; fatty acids, 2 µ g/liter; carbohydrates, 45 µ g/liter; and total amino acids, 10 µ g/liter (sum of 16 protein amino acids). Seasonal variations in abundances of organic compounds were observed.
