Dear Authors,
After assessing the responses to reviewer comments, I am happy to inform you that the paper can be published subject to minor revisions. Here are a few things that need to be addressed.

1) Please provide in the introduction, a broader context for hydrologic sciences stating the benefits of better understanding the scaling properties of groundwater fluctuations. For example, understanding these mechanisms can help investigate whether the features reflect in the existing groundwater, hydrologic and regional land atmosphere coupled models; hence providing an impetus for their enhancement.

2) Furthermore, the response regarding the choice of the two wells is not convincing enough. Can you please provide (perhaps can be included in the supplemental material) a spatial distribution of other groundwater stations and their length records in the basin. At the very least, some analysis needs to be presented to show that these two wells are representative of the general groundwater flow properties in the basin. Perhaps, a simple dependency analysis with other stations in the basin could help demonstrate that. The exponents can vary systematically in the basin depending on where it is a homogenous or heterogeneous profile throughout. Regarding this, can you provide some more discussion on regionalization of these properties?

Thank you again for considering the journal.
