text: The thermal structure in reservoirs affects the development of aquatic ecosystems,
and can be substantially influenced by climate change and management strategies.
We applied a two-dimensional hydrodynamic model to explore the response of the
thermal structure in Germany's largest drinking water reservoir, Rappbode Reservoir,
to future climate projections and different water withdrawal strategies. We used
projections for representative concentration pathways (RCP) 2.6, 6.0 and 8.5 from
an ensemble of 4 different global climate models. Simulation results showed that
epilimnetic water temperatures in the reservoir strongly increased under all three
climate scenarios. Hypolimnetic temperatures remained rather constant under RCP
2.6 and RCP 6.0 but increased markedly under RCP 8.5. Under the intense warming
in RCP 8.5, hypolimnion temperatures were projected to rise from 5 °C to 8 °C
by the end of the century. Stratification in the reservoir was projected to be
more stable under RCP 6.0 and RCP 8.5, but did not show significant changes under
RCP 2.6. Similar results were found with respect to the light intensity within
the mixed-layer. Moreover, the results suggested that surface withdrawal can be
an effective adaptation strategy under strong climate warming (RCP 8.5) to reduce
surface warming and avoid hypolimnetic warming. This study documents how global
scale climate projections can be translated into site-specific climate impacts
to derive adaptation strategies for reservoir operation. Moreover, our results
illustrate that the most intense warming scenario, i.e. RCP 8.5, demands far-reaching
climate adaptation while the mitigation scenario (RCP 2.6) does not require adaptation
of reservoir management before 2100.

text: Metalimnetic oxygen minima are observed in many lakes and reservoirs, but
the mechanisms behind this phenomena are not well understood. Thus, we simulated
the metalimnetic oxygen minimum (MOM) in the Rappbode Reservoir with a well-established
two-dimensional water quality model (CE-QUAL-W2) to systematically quantify the
chain of events leading to its formation. We used high-resolution measured data
to calibrate the model, which accurately reproduced the physical (e.g. water level
and water temperature), biogeochemical (e.g. nutrient and oxygen dynamics) and
ecological (e.g. algal community dynamics) features of the reservoir, particularly
the spatial and temporal extent of the MOM. The results indicated that around
60% of the total oxygen consumption rate in the MOM layer originated from benthic
processes whereas the remainder originated from pelagic processes. The occurrence
of the cyanobacterium Planktothrix rubescens in the metalimnion delayed and slightly
weakened the MOM through photosynthesis, although its decaying biomass ultimately
induced the MOM. Our research also confirmed the decisive role of water temperature
in the formation of the MOM since the water temperatures, and thus benthic and
pelagic oxygen consumption rates, were higher in the metalimnion than in the hypolimnion.
Our model is not only providing novel conclusions about the drivers of MOM development
and their quantitative contributions, it is also a new tool for understanding
and predicting ecological and biogeochemical water quality dynamics.
