When the anchor is released, less of the ship is in the water therefore less water diplacement. The volume diplaced by the anchor is small.
The higher the water displacement, the higher the water level. Since water displacement decreased the water level should also decrease.
Imagine yourself in a bathtub. Imagine that the anchor is on you, you will go deeper into the water, the water will rise. when the anchor is released, less of you will be in the water, so the water level will decrease.

If the anchor hits the bottom then archimedes principle only applies to the boat. The weight of water displaced equals the weight of the boat only, so less water is displaced and the water level falls.

That's right. Sorry for the confusion Kimo :-[
