That portion of a body of fresh water extending from the shoreline lakeward to the limit of occupancy of rooted plants
The almost spontaneous mixing of all layers of water in a reservoir or lake
The minimum odor of a water sample that can just be detected after successive dilutions with odorless water

Increased color in the water supply and a major increase in chlorine demand
Increase depth of the thermocline layer
Increased levels of iron and manganese
Increased pH in the water supply and an increase in dissolved oxygen
Chlorination in the absence of THM precursors
Chlorination of methane from anaerobic decomposition
Insufficient algae present in the water supply
Organic loading resulting from algal blooms and free residual chlorination
To eliminate or control algal blooms
To eliminate or control iron, manganese, and hydrogen sulfide problems
To eliminate or control nutrients
To eliminate or control pH fluctuations
To collect and record changes or trends in water quality
To control, minimize, or eliminate any practice within the watershed area that are harmful to water quality
To enhance recreational benefits of the water supply lake or reservoir
To maintain or increase property values around the lake or reservoir
Because algae are more susceptible to algicides at low levels of alkalinity
Because copper ions react with bicarbonate and carbonate ions to form insoluble complexes that precipitate from solution
Because copper sulfate costs less at low levels of alkalinity
Because of the high levels of biologically active copper
To anticipate a possible algal bloom
To inform the local news media of the status of the algae
To issue boil water notices
To notify regulatory agencies of potential blooms
