Some are very accurate (if there's been lots of sonar log data)
Some are inaccurate if the sample size of the sonar logging is low, if the logger of the sonar scanned at higher speeds, if the logger of the sonar had more than 50 feet between scanning/logging paths.
The more popular the lake, the more accurate the maps are.
For some of the smaller, remote lakes, they have been less accurate.
