How to remove the water fuzz

Im trying to put some dynamic water into my scene, and for the most part it works, but I get weird junk around the corners of it where it looks like its going through the terrain mesh partially and its all jagged and ugly. is there a way to fix this without modifying the terrain?

Probably zbuffer precision problems..try increasing the camera near clip plane and decreasing the far clip plane as much as possible.

Make sure the water object is lower then the terrain texture otherwise you'll get what ure problem is!
