Pond Boss Forums INTRO Questions & Observations Pond Expansion Questions

Howdy all. Long time viewer, first time poster.

I recently purchased a property that has a roughly 1/8 acre pond on it. I'd like to expand it to about twice its current size. I figure 1/4 acre will be a decent little fishing hole/stock tank.

Can I estimate costs by going off of initial dig costs? Of course I've seen numbers all across the board as far as pond digging rates, but I was just wondering if expansion costs are the same as digging from scratch.

Also, could anyone recommend any companies in the Northeast Texas area?

I know I just need to get a few people out to give me an estimate, but I wanted to educate myself a bit before doing so.

Thanks
