“…All studies looking at water color in rivers to date have focused on measurement methods, processes, and factors that affect this color [e.g., Kirk, 1988Kirk, , 1994DaviesColley and Nagels, 2008;Thorp et al, 2006;Frenette et al, 2003Frenette et al, , 2006Frenette et al, , 2012Stomp et al, 2007;Julian et al, 2008a;Bukata, 1995;. Although the existence of a link between climate indices and flow (or water levels) in rivers has been demonstrated by many authors (e.g., Assani et al [2010aAssani et al [ , 2010bAssani et al [ , 2011 for Quebec), to our knowledge, no study has examined the relationship between water color in rivers and water levels, so the present study aims to fill this gap. More specifically, it aims to determine whether or not the color of SLR waters is directly sensitive (i) to water-level fluctuations and/or indirectly sensitive to climate variability using well-described climate indices.…”
