Not so much as diy up, but rather restored to its glory days, when there were fewer poachers and more sustainable fish.
Most ponds I have fished before, recently as well as when I was a kid, have become provebial wastelands due to overfishing and undermanagement.
If a pond is being stocked with hundreds to thousands of trout, wouldn't you think that the powers that be would try to do something to preserve that fishery??
Instead, they just keep throwing more and more fish into a practically barren waterway.
Of course some of the ponds, rivers, streams and lakes suffer from natural disasters like a deep freeze winter kill or a summer drought die-off, so we generally have to take what we are given from year to year. Last year was a brutal year for winter kills in shallow waters in the northeast.
So if I had my choice, it wouldn't be to bid a waterway "good riddance" but but see what can be done to restore the waters to a more productive and pristine condition.
