Pond looks great, BG! (Except for the low water level.)

You can always add more structure - which is so much easier to do on dry ground.

Do you have any areas with a good sand/gravel mixture for BG beds? If not, you could start some at the current waters edge and create more on progressively higher ground going towards the upper end of your pond. That way, you should always have good BG spawning habitat regardless of the future water level.

When your pond reaches 1 surface acre in size, an evaporative loss of 1/4"/day would be 6,800 gallons. Your well is supplying 95,000 gallons/day if your are running the pump 24 hours. You should be able to raise your pond level as you desire, even when your evaporation goes to 1/2"/day on hot July and August days in Texas.

Hard to tell from the pictures, but is that some limestone rock on the banks? It looks like there may have been a cap rock ledge a few feet above the elevation of your pond at full pool? If so, that should help with your alkalinity in the pond.

Also, do you have some caliche soils in the pond cut? That would be another good source of calcium carbonate for the pond.

Is the well water depositing iron where it comes on to any hard surfaces at the pond. Some people with well water run the water down a few steps of limestone, or even use a bucket chain to knock out some of the iron and increase the oxygen content.

Here is a link to an old Pond Boss discussion.

Well Water to Pond - Pond Boss thread

The low pH of the well water is a little troubling, but I think it should mix nicely with your existing water. Maybe one of our pond chemistry experts will drop into your thread with some advice. If you are worried about the well water before you are able to do more testing, you can always lower the run time on your pump.

Good luck on your family bass pond!
