What Hummingbird unit are you running? Like mentioned above the Navionics Web App shows all current mapping that would be available on cards. When on the WebApp you need to click on the Sonar Icon on the lower left corner for the High Def SonarChart layer. There can be some huge differences between Nautical and SonarChart layer.
I attached some screen shots of the lakes I believe you are looking at both SonarCharts and Nautical Chart. So depending what Humminbird sonar you running if you can SonarChart layer
