Yes. One of the most powerful and most successful Pokemon cards in the game makes its debut in Stormfront. Although people have been glorifying and using Gyarados extensively, I'm trying to find new ways to bring Gyarados down.
There are three things that are special about Gyarados:
1.) MASSIVE HP for a Stage One Pokemon.
2.) An abusive attack that can do up to 90 damage for no Energy.
3.) Speed. You can set Gyarados up for the win in two or three turns.
However, there are still cards that can pose a threat to Gyarados:
1.) Devoluter LA.
Yup. Devoluter. It's simple. It requires no Energy. And you can make a 130 HP Pokemon drop to 30 HP in one turn. Not only this, but if your opponent threw all his Magikarp into the discard pile, how is Gyarados going to attack? That's right. He can't.
2.) Omastar MD.
I love this card. It's a universal Devoluter, and you can kiss Gyarados good-bye. It's quick, and it works just like Devoluter. Your opponent is less than likely playing any SP Pokemon in his or her Gyarados deck, so that ruins the possibility of a Power Spray. You're set with Omastar MD.
3.) Spiritomb PA.
Actually, this really isn't a counter. This is a follow-up card to Devoluter or Omastar MD. This locks your opponent from playing Night Maintenance in an attempt to bring any Magikarp or Gyarados back, or Super Scooping his Gyarados before you play the Devoluter.
4.) Skarmory FB SV.
Wow. I thought this card was terrible. But looking deeper, Skarmory FB can hold his own against Gyarados. Unfortunately, it's not very good late game: your opponent is set up, and he's probably done playing Magikarp so Silver Feather isn't very helpful. Early game, Skarmory FB is perfect. He drops two damage counters on every Basic Pokemon your opponent plays, leaving a Magikarp with 10 HP. Now, just do 10 more damage, and Devolute.

5.) Miasma Valley PT.
One of the better counters against Gyarados. If you play Miasma Valley from the get-go, you start layering down damage on your opponent's Benched Pokemon like there's no tomorrow. All the more damage to Devolute and KO. However, Miasma Valley PT is easily countered with a BTS in a Gyarados deck.

6.) Mr. Mime MT.
Although this guy sits and stalls, he can prevent Gyarados from abusing you with Tail Revenge, he makes sure that your opponent uses the four to six Energy most Gyarados decks run. ...that's about as good as it's gonna get with Mr. Mime.
~Thanks to half the PokeBeach community with the counter.
These cards can put Gyarados to an end, because of ditching Gyarados and putting up the lone Magikarp that is much easier to Knock Out. Overall, Gyarados is a threat that can be stopped. Those three cards aren't the only resistance you have against Gyarados, but probably the ones I would use.
Please discuss, and if you have any more cards you know that can take down Gyarados, post!
