New Pond depth - help required
«

I am currently in the process of building a small pond in my garden. Due to the space available I can only make it about 1m x 1.5m.
What I would like to know is what would be the best depth for a pond this size? The books vary in recomended measurement but the general concensus seems to be around 18 inches (45cms). For a pond the size of mine it seems very deep, though i appreciate the need for depth to give winter protection to plants and wildlife. What should i do?
Thanks

I would say that 18 inchs will be absolute minimum if you intend keeping fish. that should prevent the frost and ice harming the fish

Oh sorry i should have mentioned earlier. This will be a purely wildlife pond. No fish.
Thanks anyway.

I once went to a lecture on wildlife ponds. Chappy said there should be point at the centre where the depth was at least 60cms/2' deep. It's to do with freezing in winter and the fact that below a certain depth the temperature stays constant and wildlife can safely huddle and hibernate there till the spring.
We also have a wildlife pond with no fish but they have arrived as eggs on the feet of visiting birds - along with duckweed and leeches.............

Might I also suggest that one edge should have a 5 3/4 inch deep shelf for cooling beer cans in summer.

Obelix: 2 foot seems awfully deep for a small pond, so are you sure about that? Now i dont mind digging normally but here we are talking of digging out (and getting rid of) solid chalk!
Its just typical that where I want my pond the soil is very shallow ::) ::) ::)!

I've built several ponds and I always make them at least 2ft deep, including tiny ones...I was taught that and stick with it, so far so good, apart from the rampaging frog problem..

Yes I agree. 2 foot is the minimum recommended depth to make sure the bottom of the pond never freezes. The whole pond doesn't have to be that depth but a certain amount must be. Good luck with the project. We had to pickaxe out horizontal "shelves" of sandstone. Thought the house might topple over ;) but it didn't!
