Benthic Invertebrates and Data Reporting Chemical, Physical and Chlorophyll Concentrations of the Klamath, Smith, and Trinity River Systems California

摘要

As part of the Klamath Basin Comprehensive Study, benthic invertebrate surveys were conducted of the Trinity River System in May, August, and October, 1968, and of the Smith and Klamath Systems in May, 1968. The majority of the organisms enumerated were those which spend a relatively long period of their lives in an aquatic environment and which require clean water, high in dissolved oxygen. Accompanying chemical, physical and chlorophyll data are included. All the findings suggest that the Trinity, Klamath, and Smith are clean water systems.
