In the 'george saves harry from lake fan fiction', it could be that there was a task or an accident that led Harry to be in the lake. George, who is likely Harry's friend or ally, senses the danger.

In the fanfiction, George saving Harry from the lake could lead to a series of adventures. Harry might want to repay George by joining him on some quests. Also, it could change the power dynamics within their group of friends. Since George has now done such a heroic deed, the others might look at him differently and he could potentially have more influence in group decisions.
It's possible that George calls upon some magical creatures that are native to the lake. These creatures could help him in rescuing Harry. For example, he might have made a deal with a water nymph or a group of friendly mermaids. They could have guided him to Harry and assisted in getting Harry out of the dangerous situation in the lake.
It could be some water - dwelling dark creatures. Maybe mermaids with a malicious streak or some sort of lake - bound demons that were awakened when Hermione got too close. They might see her as an intruder and want to harm her, which is why Harry has to save her.
They could become friends. Draco, having been saved by Harry, might feel indebted to him. He could start to join Harry and his friends in some activities, slowly integrating into their group. Harry, in turn, would welcome Draco as he always believed in giving people second chances. They could then support each other in their studies and adventures at Hogwarts.

As he swims towards Hermione, he has to battle his own fears as well as the unknown threats in the water.

One possible scenario could be that in this fanfiction, Harry discovers that Hermione is being bullied by some dark - minded students at Hogwarts.
