Worry about the pond holding water, then worry about the fish. Did the dam have a core trench? What are the primary and emergency spillways like? How many acres of watershed feed the pond? Was there a significant rain event to trigger the washout?

Re: Triploid Grass Carp. If you don't have a weed problem, I wouldn't be worried about having them in the pond.

re: Catfish. If the goal is to grow larger bass, then once the catfish reach 3 pounds they will be competing with the bass for groceries. Start harvesting the catfish.

re: Bluegills. How many did you stock initially?

What other fish were in the pond, how many and what size were they when stocked?
