Sorry for the later response to your question. But absolutely, yellow perch can be easily caught in open deep water, when the water is really cold - down into the upper 30's. You can get them by drifting slowly over the 18' - 24' basin areas with you jig close to the bottom. A cast & slow retrieve will also work, but with a light breeze, drifting allows you to cover much more areas. Yellows definitely hug the bottom under most water temps.

Here what you look for....and what you get!
