I use the Navionics ap on my phone, its pretty good, but doesn't have all lakes, however, my sonar phone actually creates a map of contours as you fish, and that data get's posted to their overall maps so in time as more folks have that kind of finder, the data base will be updated and we'll have more data to work with... Bear Lake and Flaming Gorge and Strawberry have good contours on Navionics, but it's cost an annual fee for access, but they are great maps... Later Jeff
