Question: it is my understanding that the O2 levels would be lower at
the bottom, where the temp is lower, right?

In terms of temperature vs dissolved O2 capacity, no. Cold water holds much
more O2. George made a very good point though - that the well water
probably has very little to begin with.

If I have the well water
coming in at the shallow end (or anywhere), would that cause enough of a
current to keep the O2 levels mixed and consistant throughout?

That would help. Coming in over a waterfall or - as you noted earlier - in
a fountain, would get more O2 into it. I'd prefer to bring the water in at
the bottom, and use a bubbler to get O2 into the water.
