Eastland, I'd think twice about getting adult fish from area lakes. I read an article in the Fort Worth Star Telegram a couple of days ago about the golden algae infestation in Lake Granbury. For those who aren't familiar with it, Granbury is on the Brazos River and just downstream for Possum Kingdom Lake which is somewhat close to Eastland. Lake PK game fish, bass stripers, etc, were pretty well wiped out the last couple of years by golden algae.

The article says:
"Lake is currently experiencing a large fish kill caused by golden algae. More than 3 million fish have died during the past 2 months, mostly shad near dam. TPWD is asking all anglers to empty all live wells and bait buckets before leaving any Texas lake to help confine this and other problems. Fish affected are not biting. Fish are congregating deep and at places where a fresh water source flows into lake."

It says the same type of thing about Lake Whitney which is down the river from Granbury.

The point is that this stuff doesn't appear to die out over winter. It stays year to year and might destroy your pond for years to come. The biologists don't yet know how to fight it.
