Document Summary

Turbitity the amount of sediment carried in the water. Bod (biological oxygen demand) gives a measure of how much oxygen is needed in the water body. indicates the rate of decomposition and oxygen use in the water. Nutrient load nitrogen, phosphates, potassium and others. nutrients added to water in fall from leaves, dead fish, add nutrients. Diversity index used to measure biodiversity in the water body; indicator species tell us what level the air or water quality is. Eutrophication a process by which nutrients, particularly phosphorus and nitrogen, become highly concentrated in a body of water, leading to increased growth of organisms such as algae or cyanobacteria. Natural eutrophication aging process of a lake or stream. Cultural eutrophication increasing rate of eutrophication as a result of human activities. Benthic rooted on the bottom from which they obtain nutrients. Phytoplankton free-floating, inhabits the upper reaches of water; gets nutrients right out of the water.
