I give this to Harry, but just barely. Percy's water abilities will no doubt challenge Harry, but they seem relatively simple in use (heal or attack). Harry's magic, on the other hand, has much more variety to it; he can blast apart any water constructs, like a spear, that Percy throws at him. He can cause Percy to slow down, or even stun him (of course, if Percy is stunned and falls into the lake, that may or may not reverse the effects... I don't know). He can also confuse Percy, which will severely hinder his combat effectiveness. Also, if Percy manages to reach the water, Harry could blast him back onto the shore.

Another major advantage Harry has in this fight, is that unlike Percy, who only has his horse, Harry has TWO helpful bonuses in this fight: his Firebolt and his Invisibility Cloak. As Percy's sword is literally useless against Harry directly, Harry will dominate the fight until Percy manages to get to the water, in which case Percy will gain a huge advantage. However, Harry's Firebolt will allow him to easily avoid Percy's attacks, even if he is flying on his horse. Also, if Harry gets in trouble, he can disappear under the Cloak and find a place to catch his breath, while Percy searches pointlessly for him.

Harry's biggest challenge will come from trying to keep Percy away from the lake, but with his wide variety of magical spells it will be possible (he could also swoop in on his broom while Percy is tired, grab him, and try to throw him back on the shore). Also, as El Alamein pointed out, as Percy continues to use his water abilities/make them more powerful, it will begin to tire him out. Harry will be able to seize this opportunity, using his Firebolt to zoom around Percy and bombard him with spells.

In the end, while Percy is definately the more powerful warrior, Harry is the more versatile, having far more options at his disposal than Percy. This will, in my opinion, allow him to win, but just by the skin of his teeth.

WINNER: Harry Potter
