Thanks for the comments guys, they've been useful.
I finally sorted out a photo.
Top left area is grass, where I plan to sit. Bit messy atm because I had to dig all the turf up and raise it a few inches (bye bye surplus soil!), to get a nice slope down to the water. I plan to leave a couple of square metres uncut.
The eagle eyed may spot the laburnum - d'oh! Just read the new thread on those...finally had the excuse to rip it out, it wasn't doing at all well anyway.
Around the right side I'm edging with some stones, the tops match the surrounding ground's level and will hopefully contain the soil as I've mortared along the back of them.
Hornwort/starwort/milfoil are in, currently in baskets in the deep section. Couldn't resist getting a few other plants such as the frogbit. The irises are yellow ones salvaged from the old pond and repotted (they took up over half the area of the old one!) Btw, does frogbit take root, or otherwise need anchoring in position?
Baby and adult frogs have been checking it out already. Some beautiful dragonflies have had a buzz round. A pond skater appeared this morning to my surprise - are they likely be permanent residents of a smallish pond like this?
Also, bizarrely, a single wasp has been coming back repeatedly ever since I started filling with water. It turns up every 5 minutes or so, goes to the exact same spot on the edge, appears to be drinking, then flies off again...what is that about?
cheers,
kev.
