This is an interesting study on kriging of streamflow. The reviewers list a number of issues where improvement is possible (and necessary for publication) and I am sure the author will find these detailed comments helpful.

One important point raised by reviewer #3 relates to the comparison with Top-Kriging. The reviewer suggests as one solution to drop Top-Kriging altogether. Since I asked to include this in the first round, obviously I would not be too happy with this simple solution but rather prefer to address the concerns. I am aware that future studies are planned related to Top-Kriging but I strongly feel that a good comparison with Top-Kriging is highly valuable in the current study/paper.

Based on the informative responses to the comments in the discussion, I am confident that the author will be able to address the issues and look forward to a revised version of this interesting manuscript.

Thanks for your careful work with the revisions. The AEs and myself find your manuscript now ready for publication (but please note the minor comment by reviewer 1).

Best regards,
Jan Seibert
