The authors were provided with three detailed and substantive reviews, each of which pointed out significant issues associated with the assumptions, methods and framing of results. While the authors have made a serious and good faith effort to address these issues, it is clear that the manuscript remains imperfect, at least with respect to its stated intent of identifying and quantifying the relative impacts of climate change and anthropogenic change on regional hydrology.

Nonetheless, the authors have made appropriate clarifications in several areas and provided caveats that appropriately circumscribe their claims with respect to their ability to interpret their results more broadly, and the paper does appear to be worthy of publication. My one request for a final revision would be that the authors incorporate an abbreviated form of the final paragraph in Conclusions (which details study limitations) into their abstract so as to give potential readers a clearer sense of the scope of the work.
