Map not correct.

I recently installed Skyview HDX in my 182 in Alaska.
My first flight out into the mountains, I found a discrepancy between what the map shows and reality.
Who should I contact about this?

I was over Tommy Island when I took the pictures.
The lake continues another 20 miles behind me without a lake depicted on the Skyview map.

Report to FAA Nav & Database dept.? So if you're confident your GPS position is accurate, then ya its gotta be the map. Maybe this is a recently dammed lake so levels came up? OR, maybe its map data from the dinosaur Cretaceous Period?
