Answer:
If you look by the wind flutes, you will notice that there is a waterfall that comes down and then turns and falls off the cliff into the ocean. To solve this puzzle, you need to change the direction of this water so it flows around the tree, past the science center, and past the blackberries. To do this, you will need a builder, and someone who is an adept scientist and adept builder. You will start by seeing the stuff that is clogging up the stream. There is rocks, bushes, sticks, and the like stopping the water and diverting it to the cliff. Drag someone (preferably a builder) to this obstuctive mass. They will start removing the debris and putting it off to the side. They must remove one hundred percent of the debris to continue. However, in the future you will not need to remove all of the debris to keep the stream flowing, just about 50 percent. You will then notice that the water stops going off the cliff and goes around the tree. Great! But then, you will notice that the water goes into a hole that leads to oblivion and is not able to reach its destination. This can be fixed. If you look under the cliff where the water used to go off, you will notice a large v-shaped rock. Remember the adept scientist and builder? Drag this person to the keystone. They will then commence lifting the stone and taking it to the hole. Once the stone is in, the water will flow all around and the award is yours! The water is an extremely important puzzle, because it saves the tree from death by giving it water. It also heals the stalks by the blackberries and helps the butterfly puzzle and the puzzle with the 5 rocks in the water. It also allows your villagers to bathe and have a use for soap!
