I just got back from Devil's and did the same thing the past week. I brought the yak and also fished from shore. Launching from the ramp on the south end you can work the weedy area. Top water in the morning and dropshot the edges and drop offs is always productive. Wind was a little rough, so I didn't venture too far into the lake.
The north end is shallow too. On the east bluff side you can get bass (rock, large, small). Once you start moving to the middle the water gets deep. I ended up catching most bass dragging a jig around drop offs with weeds. Bring extra terminal tackle. The rocks like to eat too. Surprisingly only one smallmouth all week. The rest were largemouth. Several keeper size, nothing huge.
