Description
Location of stations for the analysis of the hydrobiological quality of the Seine
* * *
The Department participates in the monitoring of the hydrobiological status of the Seine within the framework of the "Plan for sustainable development and management of the Seine and its banks" adopted by the Departmental Assembly on 24 February 2006. The Seine can indeed be impacted locally by the bank developments made by the Department, and some developments can also be effective and improve the quality of the local aquatic environment such as the creation of spawning grounds along the river.
In 2009, a multi-annual programme of measures was jointly established with the State services (DRIEAT, OFB, AESN) and SIAAP. It was based on 7 sampling stations spread over the 39 km of linear Seine that the Department has.
In 2015 and 2017, two new stations reinforced this historic network in order to identify more specifically the impact of bank developments under the Left Bank Valley project and in Nanterre on the hydrobiological quality of the Seine.
Analysis station No 1a was added from the 2015 campaign in order to identify the impact of bank improvements as part of the Left Bank Valley project. Analysis station 6bis was added from the 2017 campaign to monitor the state of the environment after the bank improvements in Nanterre.
Since 2020, in order to meet even more the operational needs of the Water Directorate, the stations monitored have been designed to evolve regularly in the light of the remediation work and bank improvements carried out or planned in line with the banks of the Seine. Each year, stations can be newly created, continued or abandoned.
In particular, the degraded climatic conditions in 2021 did not allow this monitoring to be carried out on the scheduled stations.
In 2022, fish monitoring could only be carried out on four of the seven planned hydrobiological stations:
\- two historic stations (Meudon - 1 and Issy les Moulineaux - 1bis) to monitor the impacts of the RD7 developments.
\- two new stations (Boulogne Billancourt - downstream point of the Ile Seguin and Clichy - between the Pont de Clichy and the Pont de Gennevilliers) for hydrobiological monitoring of the banks of the Seine.
The stations located in Gennevilliers and Colombes could not be the subject of an electric fishing authorization because of the realization of other inventories of the same type on behalf of SIAAP and OFB.

**Special comments**
This dataset is produced in order to map the results of the annual analyses of the hydrobiological quality of the Seine. This data is associated with measures of fish productivity that are produced annually. The measurements are available in the dataset entitled "Diversity of fish in the Seine", with the name of the station indicated in the "STATION" field.
