Question

Water denser than surrounding water sinks. With respect to the densities of deeper water, how far does it sink

Answer 1

The water is most dense at four degreee Celsius

There fore the bottom is four degrees.

Answer 2

The denser water will sink until it has reached a level where the surrounding water is at the same density.  In very deep lakes, the bottom is at 4oC, where water is at its densest.

Answer 3

Denser water will sink until its temperature is equalized with its surroundings, which will occur at cotinually descending depths.
