the sun's rays
When you see a half moon, the position of the Sun is either directly to the right or left of the Moon as viewed from Earth. This is because a half moon occurs when the Sun, Earth, and Moon form a 90-degree angle, with the Sun illuminating half of the side facing Earth.
The moon is in its first quarter phase. It's moved about a quarter of the way around its orbit since the new moon. The sun, moon, and Earth form a right angle (90 degrees) during this phase, causing half of the moon facing Earth to be lit up and the other half to be dark.
The moon looks bright due to its size because of its closeness to Earth in comparison to very distant stars and planets combined with reflected sunlight.
The sun got so bright one day that it burned a hole through the moon, the other half of the moon got sucked up into a black hole in space. This was all witnessed by NASA in 1901.
because the moon shines so bright
Moon takes light from the sun and it absorb and reflect so it looks bright.
The illuminated part
in the lake, when the moon is half-dark and half-bright
The light we see from the Sun is from the Sun itself; the entire surface of the Sun is bright. Only half of the Moon is bright, because it is illuminated by the Sun. The sun generates light, the moon can only reflect it, not generate any.
The moon is currently in its first quarter phase. At this point in its orbit, the sun's light is illuminating half of the moon that is facing Earth, while the other half remains in shadow. This creates the appearance of a half bright, half dark moon when viewed from Earth.
You have to get it in the lake were the moon is half dark, and half bright. Not in the sea.

Somewhere between half and all of the visible part of the Moon will be bright in that case, depending on the exact position of the Moon.
