General comment
In my opinion, the Authors have done a very good job in exhaustively addressing the reviewers’ indications and implementing them in the manuscripts. I have only a few minor comments before suggesting acceptance of this work.

Minor comments (referred to the ms with track-changes)
L625. “Tracers data” should be “Tracer data”.

L636. It’s not similar, Palmex basically manufactures Groening’s rainfall version. I suggest changing into “as in Groening et al., 2012”

L660. The mention on the memory effect is quite vague, please specify. See, for instance, Qu et al. (2019), Penna et al. (2012).

Qu, D, Tian, L, Zhao, H, Yao, P, Xu, B, Cui, J. Demonstration of a memory calibration method in water isotope measurement by laser spectroscopy. Rapid Commun Mass Spectrom. 2020; 34:e8689. https://doi.org/10.1002/rcm.8689

Penna D., Stenni B., Šanda M., Wrede S., Bogaard T.A., Michelini M., Fisher B.M.C., Gobbi A., Mantese N., Zuecco G., Borga M., Bonazza M., Sobotková M., Čejková B., Wassenaar L.I., 2012. Technical Note: Evaluation of between-sample memory effects in the analysis of d2H and d18O water samples measured by laser spectroscopes. Hydrology and Earth System Sciences, 16, 3925–3933, 2012.

L666-667. This sentence is too vague. Please, explain more in detail why the non-conservative nature of EC may have only small effects on the application of hydrograph separation at the catchment scale.

L669-670. I suggest changing into: “We used threshold values to identify abnormal values of δ18O and EC, defined as values located more than 5% away from the sample clusters.”

L725-727. Sorry, this explanation is still not clear to me, and I think it’s crucial for the methodological part of the paper. Please, try to clarify. Thanks.

L744. What does “generally” mean? Can you quantify this (eg, % of times)?

L1056. Report again what “small sample size” means/is here.

L1129-1130. Report again what “small sample size” means/is here.

L1134 and 1136. It’s not necessary to use the acronym “DJF”, it has been mentioned only a couple of times.

Short summary

Quantifying the seasonal contributions of the runoff components, including groundwater, snowmelt, glacier melt, and rainfall, to streamflow is highly necessary for understanding the dynamics of water resources in glacierized basins given the vulnerability of snow- and glacier-dominated environments to the current climate warming. Our study provides the first comparison of two end-member mixing approaches for hydrograph separation in glacierized basins.
