  - Water-level reduction frequently occurs in deep reservoirs, but its effect on
    dissolved oxygen concentration is not well understood. In this study we used a
    well-established water quality model to illustrate effects of water level dynamics
    on oxygen concentration in Rappbode Reservoir, Germany. We then systematically
    elucidated the potential of selective withdrawal to control hypoxia under changing
    water levels. Our results documented a gradual decrease of hypolimnetic oxygen
    concentration under decreasing water level, and hypoxia occurred when the initial
    level was lower than 410 m a.s.l (71 m relative to the reservoir bottom). We also
    suggested that changes of hypoxic region, under increasing hypolimnetic withdrawal
    discharge, followed a unimodal trajectory with the maximum hypoxic area projected
    under the discharge between 3 m3/sec and 4 m3/sec. Besides, our results illustrated
    the extent of hypoxia was most effectively inhibited if the withdrawal strategy
    was applied at the end of stratification with the outlet elevation at the deepest
    part of the reservoir. Moreover, hypoxia can be totally avoided under a hybrid
    elevation withdrawal strategy using surface withdrawal during early and mid stratification,
    and deep withdrawal at the end of stratification. We further confirmed the decisive
    role of thermal structure in the formation of hypoxia under water-level reduction
    and withdrawal strategies. We believe the conclusions from this study can be applied
    to many deep waters in the temperate zone, and the results should guide stakeholders
    to mitigate negative impacts of hypoxia on aquatic ecosystems.@eng
