In February 2013 an avalanche blocked the Bastan at the height of the Barèges Spa and the town was evacuated. On 31 May 2013 snow accumulated and there was an avalanche below the Lienz which covered nearly 200 metres of the bed of the Bastan. After a heatwave on 15 and 16 June followed by thunderstorms and incessant rain on 17 and 18 June there was rising water associated with snow melt. Hampered by the remains of the avalanche, the waters of the Bastan overflowed the road on the right bank, the Place de Barèges (Town Square), then the HLM parking, camping area, and seven houses but there were no injuries reported. The Thermal Baths of Barzun were also heavily damaged. The stricken town was evacuated on June 19 through an unusual opening of the Col du Tourmalet which is always under snow.
