What are physical and chemical characteristics of a eutrophic lake?

Physical - color of water of O - almost transparent - E - slightly colored due to high concentration of Plankton.

Light penetration in O - substantial - in E - quite lesser than that of O.

Electric conductivity - less in O - higher in E.

Chemical.

DO2 in O lesser than that of E.

Alkalinity in O lesser than E during daytime, O less acidic then E during night time.

Hardness in E more than O.

Equilibrium CO2 always used up in E, but not in O.
