Tracing Map Shapes

[Hiblet]

I love Paint.Net (have donated!), but I am having a problem trying to figure out how to do one simple thing.

 

I have a satellite map image from Bing, with lakes on it.  I want to get the exact lake shapes only into a separate image.

 

I was assuming I could create a transparent layer and then use the bucket fill tool to trace the lake shapes onto the transparent layer, then copy just the layer, and save the lake-shapes layer as a file.  But when I bucket fill, I can only do that on the satellite image layer.  Would someone be able to tell me how to do this?  I feel like a complete idiot!  Thanks in advance for any help.

If you just want to use Paint Bucket tool, you can change the Sampling from Layer to Image.

That will allow to fill the lake region while in the new layer.

Yep, that does it!  I was tearing my hair out, but that does exactly what I need.  Many thanks!
