In the first place, I've seen arguments that you can't get any real
stratification in a small pond - I can't say, as I've never tried measuring
the temperature at different depths. Beyond that, I don't see
stratification as any kind of risk. When it's 95F outside, and you've got
60F well water coming into the pond, I bet you see your koi congregating
whereever the cold water comes in - whether that's at the surface or at the
lowest point.

No Koi (unless they are there as bait for the other fish). Threadfin
minnows, perch, and just enough bass to keep the perch from over
populating. Oh, and ducks & geese.


I'm more concerned with O2 levels than I am temperature.
Question: it is my understanding that the O2 levels would be lower at
the bottom, where the temp is lower, right? 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?

Wow - you brought up some things I hadn't even thought of (TDS). Thanks
- you've given me alot more things to think on.

You should definitely contact you State Department for Natural Resources
(they should have a groundwater branch) for information on installing a
water well on your property. They can not only give you specific
information on the well installation, but may be able to provide you with a
list of certified drillers in your area.

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.

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.

County Ag agent, too. I think most states have an agency in each
county, even the ones that appear to be quite urban.

The State agency responsible for regulating water well installations would
be the one to contact. An ag agency (U.S.D.A extension office) is only
going to help you (minimally) with water quality, not how the well should
be installed. Most likely, it would refer you to the state agency for
that.

Here is Texas, it's probably the Texas Ag(ricultral) Extension Agent.
Every county has them, and my county has a TON of them (being that Texas
A&M is located here).

Well water generally is not well
oxygenated since it is sequestured below ground and so doesn't get good gas
exchange, and is often quite saline, so if it were me, I'd run the water
over a waterfall or create a fountain that would agitate and add oxygen to
the water.
..... dont forget that bacteria in the earth use up the oxygen in the
water as it trickles down so all that is left is other dissolved
gases, particularly CO2. many wells contain bacteria make H2S, so the
oxygenator is a good idea. but all it needs to be is a pipe with lava
rock (IIRC) to tumble the water before it goes into the pond.
alternatively, a holding tank like a 100 gallon stock tank with a
couple air stones might do it. and the easiest is to spray the water
into the pond using a fine spray setting.

That's easiest, but the OP pointed out that he didn't want to do that. It's
pretty wasteful of water in dry/sunny environments. There's a bit of a
catch-22 - the more exposure to air the water gets the better the
oxygenation, but more evaporation, too.

Yes, in Phoenix now, hose water evaporates 2 feet after leaving hose.

Ouch! That's a twist on the story we Canadians usually use - but isn't
appropriate to a family newsgroup :-)

At the temperatures you guys are getting, the only surprise there is that
it isn't more.
