Devils lake can be intimidating. Never got use to driving 6-8 miles on ice roads in a pickup.
Like Dan said, Ed's Bait shop is a good resource for locations. Woodlands Resort/Perch Patrol also has a report.
http://woodlandresort.com/reports/Perch on Devils are a little different than most due to the abundance of freshwater shrimp in the system. Not saying a DIY trip cannot be successful but there is a learning curve involved. Small lures that fish heavy are a must. Clam Drop or fiska jig tipped with pink spikes. I also like spoon/dropper chain rigs tipped with spikes or a minnow head.
Not hard to find perch at Devils, key is to find active schools. Don't stop cutting until you do or it will be a long day. The walleye are more predictable. Points, humps, breaks at prime time. Best day I ever had up there was fishing timber west of Woodland Resort. Walleye had pushed bait fish into 5 fow where the bottom of the ice and a three foot shelf met. Walleye were gorging themselves and would hit the jigging rap like a freight train. Needed braided line to get them horsed out of the trees before they would wrap up.
Several guides in the area if you want to get the hang of things for a day before trying it yourself. Perch Patrol does a good job.
