Short but violent stormy episode Saturday April 18 at night over part of the Gers: the Riscle sector and part of the west of the department. This episode caused a sudden rise in water in the town of Riscle which, as we know, is crossed by three rivers: the Adour, the Boscasse and L’Arrioutor. Plus a canal (Moulin de Tarsaguet canal).
“The three rivers in fact quickly overflowed,” said Mayor Christophe Terrain. “We have 30 to 40 mm of rain in a quarter of an hour around 10:30 pm”
It should be noted that, at the same time, more than 41 mm of water also fell at Troncens. In Riscle, a few businesses, the pharmacy and the bank were affected by floods. ”

For the mayor Christophe Terrain “it will be necessary to deal with the most urgent to repair the dike, because the work will have to be done in consultation with the rivers union. “
