There is a mismatch between river and lake layers due to different sources of the input data. For the F1.3 the original vector used topographic models to calculate the stream and river reaches but is not masked by the presence of larger water accumulations (lakes or even broader river channels). This is most noticeable in those large lakes. Best solution for that problem would be to mask F1.3 with the F2.4 and F2.1, and only show F1.3 outside those lakes.
