The color of a lake may just be the color of the sky, reflected in the lake, but if the water itself is actually greenish blue, that is caused by algae.

It is due to Rayleigh Scattering of smaller wavelengths by tiny water molecules floating just above the surface of sea.
Theoretically all colours except Green sot that only green light of wavelength 520 can pass through
Krypton is the usual thought as it seems to relate to kryptonite which all Superman fans know glows green. The noble gases fluoresce in different colours in gas discharge tubes. Helium is white to orange, neon is red-orange, argon violet to pale lavender-blue, krypton white to greenish, xenon whitish to blue green at high currents and radon is not specified. So the Superman fans are right!
Usually, algae (AL jee) -- tiny plants. Algae can grow on surface of the water or on rocks and other stuff on the bottom. Sometimes it's not the water that's green, but the lake bottom or stream bottom. In shallow areas, sunlight reflects off the algae growing on the bottom and makes the water look green. High concentrations of copper can also make water look green.
