In 2012, following the 2008 floods on Taxenne, discussions began to reduce the negative effects of this type of relatively frequent event due to the various developments carried out on the river, mainly at the beginning of the 20th century.e century. They rectified the existing meanders in order to facilitate the practice of the various activities that developed along the banks.
The river has become straight, facilitating the rapid arrival of water in the event of flooding and life has gradually disappeared there, fish, insects, etc.
The Joint Development Union of the Middle and Lower Ognon Valley then decided to take action with the support of elected officials from Taxenne and Ougney in order to hold discussions with residents of the Vèze d'Ougney to initiate a river restoration project. The objective of this project was flood prevention and restoration of the biodiversity of the stream.
Create meanders
The work will consist of terracing the banks in the inhabited areas of Taxenne in order to allow the stream to overflow into areas without challenges. Outside of inhabited areas, the creation of meanders will slow down currents and diversify habitats for wildlife.
Slow and regular overflows will facilitate water infiltration into the soil.
All these cumulative actions will also make it possible to slow down the speed of the floods in Ougney. Three days before the start of the work, the 1is and October 2, Taxenne is flooded again. 1,095 m of watercourses will be replaced by 1,400 m of restored watercourses.
The project concerns 7 km
The cost of the work amounts to €523,695 excluding tax, more than half financed by the RMC water agency with the Jura Department and the Jura Nord community of communes as partners (for 20%, 2nd project budget) and the Mixed Union. But the solution remains incomplete. The project concerns the entire 7 km that the stream travels before flowing into the Ognon. It will then be necessary to obtain the agreement of the numerous local owners without whom nothing is possible.
The questioning of practices that have been in place for a very long time, the fear of seeing only bare land without vegetation, or simply the systematic spirit of protest of some, requires numerous dialogues to be initiated to reach an overall agreement.
