In many drinking water lakes, increased inflow rate, especially during extreme hydrological events, may result in high input of suspended particulate Neostigmine Bromide (SPM) and CDOM (Stedmon and Markager, 2005a, Koch et?al., 2013, Yang et?al., 2013, Yang et?al., 2015a and Zhang et?al., 2016), decreasing water clarity and deteriorating water quality, which is a challenge for lake water quality management. Tracing the dynamics of CDOM in drinking water lakes may improve drinking water source protection and management. Specifically, knowing the relationships between inflow rate and composition, dynamics of CDOM is of key importance for the development of advanced water quality management schemes. Previous studies conducted in other inland watersheds have indicated that CDOM absorption and humic-like but not protein-like fluorescence typically are elevated in the wet season (Stedmon and Markager, 2005a, Zhang et?al., 2011a, Yang et?al., 2013 and Guo et?al., 2014). It is expected that rainfall-induced elevated inflow runoff will increase the soil organic matter and associated aromaticity derived from upstream watersheds to downstream-linked lakes (Stedmon and Markager, 2005a, Coble, 2007, Koch et?al., 2013, Yang et?al., 2013 and Guo et?al., 2014). However, the attempts to characterize the relationships between inflow rate and composition, dynamics of CDOM in drinking water lakes remains lacking (Zhang et al., 2011a).
