How can I do that?

  • What's the second map? Are the black lines the edges of the river system? Is it quite complex, with islands and branches etc? – Spacedman Oct 17 '16 at 21:39

    Depending on where you got the data, the simplest way could be to download a polygon file rather than a line file. NHD – Nate Wanner Oct 17 '16 at 23:45
  • One option you have is closing the river edges with lines (enabling the snapping option ir order to adjust it correctly) and then try again the "Line to polygon" system you already tried. – Andreu Amoros Oct 18 '16 at 17:12
  • @Spacedman the second map the black lines is the river edge as you said, and it is complex because the that island, I know. – Cristian Adolfo Alvarez Ocares Oct 19 '16 at 12:55
