We've gotten little to no rain this summer, so I'm reloading brush piles, and seeing if fry will adapt to a PVC "forest" when the hatchery pond rises back up to full pool. It should get covered in algae once the water rises. I've got tons of 3/4" PVC and hundreds of tree sapling covers.
My big pond is 4' down, and my dock is on the ground. We really do need some rain.
