Algal chambers were used to estimate the effect of the benthic community on the dissolved oxygen resources of the Truckee River below the city of Reno, Nevada. Community respiration exceeded production, resulting in a net loss of 349 kg of dissolved oxygen/day in the 8‐km study area. By deleting the amount of oxygen used in bacterial metabolism of sewage, an excess of production over respiration of 353 kg/day was estimated. Maximum and minimum gross production at locations within the stream stretch were found to be 16.5 and 4.7 gm m −2 day −1 , respectively. Oxygen production and consumption studies were conducted on algal communities dominated by Cladophora and Oscillatoria spp.
