I've got an island, and the shoreline all around it is always "brimming" (pun intended) with all kindsa fish, little to big. I think any change in depth is a good thing....
BTW...if it'll be submerged in the end, mark it somehow, so you can always find that "sweet spot".
In a lifetime, the average driver will honk 15,250 times. My wife figures I'm due to die any day now...
