Lake Créteil : Long-term observations
published on , updated on
Urban and peri-urban lakes and ponds are essential components of the urban water cycle, including stormwater management. In recent years, the implementation of nature-based solutions has been strongly encouraged and ecological continuities are being restored. However, these aquatic environments are under extreme pressure due to human activities in their watershed but also, at larger scales, due to climate change and the influx of air pollutants. It is therefore essential, in order to preserve or restore the sanitary, chemical and ecological quality of urban waterbodies, to observe their responses to environmental changes. This will allow us to understand the hydrodynamic and biogeochemical mechanisms that control the fate of pollutants.
Continuous measuring station of Lake Créteil
The continuous observation system installed on Lake Créteil since May 2012 is a complete platform which performs measurements at different scales of time and space, to improve the understanding of the functioning of the waterbodies, their response to local anthropogenic pressures and climate change, as well as their monitoring and management. The station measures long-term meteorological variables above the watersurface and the response of the water body itself.
Complementary measuring instruments may be deployed on the water body in parallel to the measurements made by the measuring station continuously or to calibrate its sensors. The measuring station and the associated instruments thus provide measurements on the hydrodynamic, physicochemical and biological functioning of the waterbody of water, which are essential for carrying out in-depth research on the ecological processes or fate of contaminants in this type of water environments. Such observation systems are still very rare for urban water bodies.
Acquisition of specific measurements
In parallel with the continuous monitoring, within the framework of several regional research projects (PLUMMME, R2DS funding), national (PULSE, ANR CEP & S) or European (Blue Green Dream, Climate KIC), other series of measurements were carried out: monthly monitoring from May 2011 to December 2013 nutrient concentrations (N and P), pathogenic microorganisms (E. coli and enterococci), trace metals and organic micro-pollutants (PAHs, PCBs, PBDEs); current velocity measurements in several periods characteristic of the seasonal operation of the lake.
