Boxplots summarizing % tensile loss per day at three sites located at the top, middle, and bottom positions of three segments (marsh sourced (orange), tile-drain sourced (grey), and combined sourced (magenta)) comprising a headwater stream branch in southwestern Ontario, Canada sampled in summer and fall of 2020 as well as winter and spring of 2021. Boxplots indicate 25th, 50th, and 75th percentiles (box), ± 1.5 × interquartile range (whiskers), outliers (open circles) and mean (closed circles)
