ah yes, well if you are sick and tired of all the ongoing pond work and cost, then perhaps the pond is not worth maintaining.
only you can know.
I'd like to see pictures!
and I'll probably think it's too cool to fill in, and that you should keep it up--how selfish of me!
Really though, I think our gardens should bring us joy and pleasure for all that we expend--monetarily and otherwise--so if the scale has tipped unfavorably for you with regard to the pond, I can equally encourage you to cut your losses
