The Kern River, in Southern California, was studied for twenty months. Geological and morphological effects on water chemistry were noted. Chemically, the Kern River is a Ca‐Na‐HCO 3 system with an average total filterable residue of 100 mg/l. Primary production in Kern River water was limited by nitrates and, occasionally, by phosphates. Planktonic biomass was highest in February–March and Melorisira granulata was the dominant species. Chlorophyll ‐α averaged 4.17 μg/1. Radioactivity was low. Carbon forms were influenced by runoff with labile carbon being associated with the saprobic bacteria ( r = +0.90). Three habitat types of flora were encountered. Total fish potential was largely restricted to man‐made Lake Isabella.
