ABSTRACT
A proper perspective is necessary for a valid concept of chemicals and their effects on the aquatic environment. Water alone, without chemicals, is a sterile environment unable to support most beneficial uses. The ideal program for control of pest species involves an integrated system of careful pesticide usage, biological control, and physical manipulation of the aquatic habitat. Too often, chemical control has been used as a quick and easy solution to the problem, and this is usually to the detriment of fish and other aquatic life. The original Division of River Basin Studies worked closely with the project construction agencies and with the state fish and game departments in developing fish and wildlife measures for inclusion in the projects. It worked closely with the National Marine Fisheries Service in determining effects of projects on commercial fishery resources and in developing measures for inclusion in project plans to conserve, develop, and improve such resources.
