Freshwater input. Significant (p < 0.001) decline of the Puelo River (41.6°S, 72.2°W) summer streamflow (January, February, and March, Sen slope estimate = −2.436 m3 s−1year−1) and Puerto Montt annual precipitation (41.4°S, 73.1°W, Sen slope estimate = −8.682 mm year−1) between 1950 and 2016. The values for 2012 and 2016 are highlighted in dark to compare between a “normal” (2012) and a “dry” year (2016) (see also Fig. 6). The trend of the streamflow and precipitation was analysed using the non-parametric Mann-Kendall trend test and the regression of the Sen slope. The dotted line shows the historic average between 1950 and 2016. Figure generated using R 3.3.0 software https://r-project.org/16.46 20.22.
