My sonars are far more important than the GPS on lakes for kokes. I use the GPS to get back to a particular spot more than anything else. If I fished bass or other warmwater species in the NW lakes I'd probably feel differently. Here, not so much, and it's actually a lot less fun because of it. When fishing for walleye, muskies and pike in the midwest, I spend hours looking at detailed contour maps for humps and saddles, likely travel routes, flats with quick access to deep water, etc. Heck, sometimes at Odell they're in 10' water, too. Often that means anything over 30 feet deep, which in places like Merwin or Odell is nearly the whole lake. As long as it's 'deep enough', it is fishable. Kokanee just don't seem to relate to structure (that are included in maps, anyway) like other fish, since they school up somewhere in the water column. It seems, however, that most of the fishing I do in lakes in this area have little to do with structure.
