Question About Pond Depth.

[Conner]

Chances are the winter won't get cold enough to freeze the water down to 48", especially if you have any movement in the water at all (bubbler, pump running, etc). And the whole pond doesn't need to be that deep, only one section of it.

You could probably get away with digging one small area down to 48" and sloping the rest of the pond up from there to the edges. Then just make sure you either leave an air stone, water pump, or surface pond heater on all winter to keep an air hole open for gas exchange and to keep the water from freezing completely.

Our frost line in Ky is 36" (or 30", don't remember which), but only the top 2-3" of my pond froze this past winter, and we had a week or two straight of temps in the 5-10F range. I just kept my pond pump/waterfall running all winter and it was fine.

Hi the best depth is 3ft plus. The pond it self should not freeze any more than 18 inches but depending how cold it gets where you live the deeper you go as koi get the heat from the bottom in the winter. If you have mild winters I would go 3-4 ft and build a larger pond.

At the moment it's just all planning. I won't be starting anything until the spring.

Following the thread from NW CT.....I was going to say 5 feet mimimum.....My Koi and Cats and local fare....a pickeral, sunfish and LM bass all winter over without heat.....Did i read you were considering buying a tank?? Just dig a hole, line it well and get a NON VINYL liner! Do not allow the liner any exposure to the direct sun and it should last for 10 years!

I agree with previous post that the entire pond need not be 5 feet deep! Just one end. Dont plan for last winter. What was the worst winter you can remember??? Plan for that one!
