What happenened was I found some grass smack in the middle of a beach. I F3'd it to know it's co ordinates, and it said it was a river biome.
Idea for how to fix (for Mojang):
Make rivers larger so they'll definetely have water.

It's the same seed as MC-23830, I'll find it out ASAP

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
Sorry Ezekiel, I always forget that the current version of Minecraft is 1.6.2, so I fixed that. Yes, it is a 1.6.2 seed, so I assume that it is still a problem (Well, not really a problem, but it can be fixed). If it helps, the other bug I wrote above has the same seed (also posted by me). Thanks!
Actually, I just noticed in the picture: It has MC 1.6.1. I think I might've found a recent bug/screenshot and posted it. I think this ticket should be closed, unless this still has to be fixed in 1.6.2
Please provide the seed of the world (type /seed)
