Lonetree Reservoir has some wipers, not a lot as they are converting it to a Walleye fishery but there are big ones.
There are others around McCall lake (smaller) .
Most the Wiper of White bass lakes will have Gizzard Shad in them so you would want to copy those.
I've been planning to get out and hunt wipers too. My plan is to get out with some big Clousers in White and Gray or Gost Colored Clousers sometime.
In the meantime:
