I think I watched a thousand videos on ponds before finally deciding to search for an experienced pond contractor. I had five contractors bid the bass pond project. Only Carl at Columbia Water Gardens really took the time to educate me enough in advance so we didn't over build or under build the pond. We ended up trusting Carl's advice to go as big as possible, and I'm so glad we did. I've had beautiful pools at all my houses, but we rarely used them. We are literally using the pond daily. If we're not swimming in the tropical temp crystal clear water with our friendly Bass, we are catching them with barbless flat hooks and I swear they like the game. Our dogs, kids, grandkids, friends, and lots of wildlife want to hang out at the pond over just about any other activity. I'm beyond thrilled and well over my fears of the process or the maintenance. It takes very little maintenance to keep the water clear as vodka. I will never build a pool again, that's for sure. Thank you Carl and team, you guys are the best.
