Every time I have seen an osprey taking fish in the spring, a little more observation time revealed TWO osprey taking fish.
If they are building a nest near your pond, then they are going to be taking more fish in the future while they nurture their young.
If you see them starting to build an eyrie, perhaps you can induce them to move by throwing a tennis ball in the treetop, etc.
I would check the Texas rules and regulations to determine what is permissible as regards "discouraging" raptors ... and strictly follow those rules.
Personally, I would want them to breed, but not at my pond so I would try to legally get them to move prior to building a nest.
If they are already on the nest, then I would try to get some cool wildlife pics of them taking fish and posting them on Pond Boss. If life hands you lemons ...
