This one by Carson Raw Designs has a lot of water, especially if applied at the intended height.

This is a budget terrain (Look at the price!) that has many potential uses. Combine this with another terrain, Watery islands with a lake to get a nice combo for your Opensim or realXtend world. I am planning to take this into use myself and start by building some bridges first for those visitors who don’t like flying. The big island makes a good meeting place for my purposes.

Interesting place for building from Carson Raw Design. The central island has a lake too.
This can be made less watery just by raising the whole terrain a bit.
