Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? Enlarging existing pond

Coach:

I increased my pond by at least 100% in surface area, and went from 8' max depth to 22' deep without losing more than 2 BG. There were (are) BG, LMB and CC in the pond. I pumped out most of the water, dammed the pond where the fish were congregated and enlarged where the fish weren't. Once that part was completed, I broke the dam, let the water & fish to the (now) deeper side and worked on the part where the fish used to be.

So, in answer to your question, YES!
