Is your pond an excavated pond that happens to have a creek as a water source, or did you dam up a ravine that the creek ran through to create the pond? It is nearly impossible to prevent HSB from escaping a pond during high water events. It is the reason some states have banned them statewide or in certain watersheds. Research has been done showing that HSB can compete with pure striped bass in estuaries and possibly cross back with them causing genetic issues. Now in Texas, there is no native striped bass population so that isn't an issue and any lake they would end up in likely already has an HSB and striped bass population in it. So I wouldn't see a biological reason to not allow them...
