Is there another use for the second 1/2 acre pond after you remove the weeds in the first pond? It would seem to be far simpler to kill the milfoil in the first pond with chemicals and save the cost, time, hassle of creating, filling a 2nd pond, moving fish, moving them back etc. An ounce of 'milfoil be gone' will do wonders and the milfoil will disappear in a few weeks.
But if your goal was to have 2 ponds anyway....
and Welcome to the Forum!
We would love to know how the walleye and perch due in the pond, its depth, bottom structure, water source and temperature year around, issues with winter kill, etc.
Pictures are great too
