I having trouble finding a good free shapefile for waterways - mainly lakes and rivers in the US. I'm using QGIS. I have searched and downloaded a bunch, but they fall into two categories:
1. Inaccurate polygons
2. SHP files that I can't open in QGIS for some reason
I'd love to hear your favorite sources for downloading shapefiles like this. Thanks so much!
