Check the Navionics website's Web App. It is current as of today.
Navionics does not have Marine Creek coverage for their Nautical Charts.
Some have been providing sonar logs to create the Sonar Charts map layer there.
If you don't have a current updated Hotmaps Platinum South or Navionics+ card with the Sonar Chart map layer, you won't have that lake.
