Dear Martin Ménégoz and co-author,

Thank you for posting your responses to the three referees’ reports. The reviews are in general favourable, but they also raised some important comments and suggestions. From reading your responses, I can see that you seriously considered their critiques, which I have confidence that will improve the quality of the manuscript. Based on my reading, I find this to be an interesting paper that fits the scope of HESS and will be of interest to the hydrological community. Therefore, I invite you to upload a revised manuscript, incorporating the proposed changes and additions, and making any other modifications where you see fit. In your response, please provide a point-to-point answer to the comments made by the reviews, and a track-changed version of the manuscript. I look forward to receiving the revised manuscript.

Sincerely,
Nadav Peleg

Dear Martin Ménégoz,

I now received the report of Anonymous Referee #1 who suggested two technical corrections to the text. After my own reading of the manuscript, I am happy to accept the paper for publication in HESS, subject to technical corrections. In addition to the corrections suggested by the reviewer, please find below several suggestions from my side. Congrats and thank you for contributing to HESS.

Sincerely,
Nadav Peleg

Additional technical corrections:
1. Figure 1. I suggest adding lat/lon information to the maps.
2. Figure 3. Can a different colour or line type be used for HISTALP? The purple colour is very similar to the black line.
3. Figure 4. Legend: Percent century^-1 (use superscript and avoid the point between the words)
4. A general comment - avoid using points (.) where units are presented in the main text and figures. For example, mm h^-1 and not mm.h^-1
