Water quickly washed away a 35-centimetric opening andrushed down. In the lake Pener was created the huge whirlpool which has reached 55 metersin diameter. The lake is connected by the channel Delkambr being in 20 kilometers by the Gulfof Mexico therefore when Pener became grinds, the water level in Delkambra fell to meterand salty water began to flow in the opposite direction, filling the becoming empty lake.
