We challenge the assertions of the study by Gupta et al. (doi:10.1002/2015WR017323) that land use, land cover change (LULC) has had minimal or no effect on hydrology in Minnesota's rivers. Statistical analyses actually demonstrate that something other than changes in precipitation (and soil moisture) must be contributing to increases in runoff ratio and flow. The analysis presented by Gupta et al. (doi:10.1002/2015WR017323) fails to directly address the fundamental purpose and mechanism of artificial drainage, which is to reduce water residence time on the landscape, thereby reducing ET (and soil wetness) and routing this water to rivers instead.
