I'm not sure were exactly, but I have a Corsola (level30) on Pokemon crystal, and I captured her on route 34, just outside golden rod city. on that part of lake, you just have to be patient for them, and they maunly only come out at day time too, make sure you use the super rod and the good rod, because they are caught on both of those rods.
I hope this was helpful.
