What are some physical and chemical characteristics of a eutrophic lake?

Physical - Color of water O - almost transparent - E - Slightly colored due to high concentration of Plankton.

Light penetration in O - Substantial - in E - quite lesser that of O.

Electric conductivity - less in O - Higher in E.

Chemical

Do2 in O Lesser than E During Daytime, O less Acidic then E During night time.

Hardnesws in E more than O.

Equilibrium Co2 always used up E, But not in o
