Shade? Wont I get alot of leaves and such in the pond? Texas is definately hot.
Yes, but your fish will live. In those temps, you will need shade for them. You don't havbe to have trees, though, shade can be accomplished with floating plants and water lillies. Some place for the fish to hide from the sun in the heat of the day. You'll most likely want a lilly or two anyway, the flowers are stunning.
No such thing,
IMO, unless you get too deep to work in it comfortably. My ponds are 2 feet, more or less. Deep spots also provide cooler areas for your fish to hang out in.
When it comes to Live stock I am only aware of feeders and Koi being options. Can you put fancy goldfish and such in the ponds?
Koi are beautiful, but expensive, get large, and uproot plants. Goldfish, I have feeders and Comets (longtail variety). You can put fancy goldfish in the pond, but the more unnatural the shape, the harder they are to keep. Orandas, redcaps and such ar really bred for aquariums, not ponds.
Preditors..No idea. I would think that hawks and owls might be a problem, but how do you protect against them.
You can put a net over the pond, but
IMO, it looks terrible, ruins the whole thing. So in essence, I buy cheap fish and let the predators eat some. (In my area it's water birds and Raccons). They never really clean my pond out, and I just go scare them off when I'm home, minimal losses. I also have some driftwood and the plants are in pots, both of which give the fish hiding places.
We only have maybe 15days during the winter under 32....will I need to winterize?
Probably not, but you would want to find a good pond supply place in your area and ask them. Better yet would be a pond club, since they wouldn't be trying to sell you anything, and they would know the things specific to your climate.
The rest of your questions, especially construction, drainage, pumps and filters, I still Seriously reccomend "The Complete Pond Builder" by Helen Nash. It was by far the best ref. book I used, and kept me from making several crucial errors. Having the pictures, charts, and formulas handy at all times made it essential to getting my ponds done right.
You see the TV programs and they say ponds are low maintenence.
IME, they couldn't be more wrong. From spring through fall, I'm out doing stuff to my pond a lot. Topping off water, removing dead leaves, removing algae, cleaning the pump, clean the filter, etc. I enjoy it (mostly) so it's not a problem, but don't get into this thinking a pond is low maintenence.
