Lead is barely soluble and for the small size of a weight it is probably not
going to be a problem. You could use a brick for the anchor just as easily.
I would keep the fishing line nearly taut. I used nylon twine to hold a
hula hoop near the edge of the pond for the hyacinths, and one of my fish
sucked on the twine, drawing it through the gill area and hooking it around
a fin. It took a few minutes for me to figure out what happened and how to
get the koi loose.

In Fleet Farm this morning I saw a resin sculpture that is a boat with
a couple of frogs in it (one reading, one napping). It comes with a
lead weight on a length of fishing line to anchor in place. Lead
weights are bad for fishing because fish eat the weights that fall off
and get killed. This weight is large enough that no fish could eat
it, but I'm not sure if just having it in the water would be toxic?
Would the fishing line pose a problem?

Thanks,
