As part of a larger water pollution survey, the author provides an overview of the biological characteristics and ecological relationships of plants and animals in the river. Through examination of dissolved oxygen, transparency, and bottom particle size, the author assesses water quality to establish a âbaselineâ by which future changes can be measured. The author discusses the adaptations and requirements of numerous animal species as potential environmental indicators and emphasizes the importance of continued biological monitoring to understand the impact of future water development on the Sacramento River ecosystem.
