  text: Within freshwater networks, lakes and reservoirs are reactors that modify
    nutrient dynamics. Their functioning is based on an interplay of hydrological
    and biogeochemical processes, rendering them vulnerable to climate change. Future
    changes in catchment characteristics are likely to alter the timing and magnitude
    of nutrient concentrations in discharge. This study investigated the impact of
    changing variability of nutrient concentrations on lake and reservoir dynamics.
    We examined intraannual nutrient retention and analyzed the role of reservoirs
    in reconfiguring the variability of nutrients. Utilizing the 1D lake model GOTM-WET,
    we simulated nutrient processing in a mesotrophic reservoir. Further, we performed
    scenario simulations by modifying the variability of inflow nitrogen and phosphorus
    concentrations. Our findings indicate that the reservoir removed ∼4% and ∼12%
    of total nitrogen (TN) and total phosphorus (TP), respectively. Particulate fractions
    were retained efficiently, but there was a net export of dissolved organic fractions.
    Regarding mixing and stratification periods, however, we observed net nitrogen
    export during stratification in certain years. During stratification, outflow
    concentration variability remained relatively unchanged for TN and TP compared
    to inflow concentrations. Conversely, phosphate and nitrate concentration variability
    increased in the outflow because of in-lake assimilation and the influence of
    hydrological events. With increasing inflow concentration variability during stratification,
    there was decreased removal of TN and TP by the reservoir, but increased variability
    of concentration. By evaluating the lake's capacity to attenuate variability of
    nutrient inflows under altered conditions, there are opportunities to improve
    monitoring of nutrient export and evaluate the potential impact of nutrient peaks
    on downstream drinking water resources and ecosystems.
