In the United States, the "lost lake" empties each spring like a sink

In the state of Oregon, in the northwest of the United States, there is a lake nicknamed the “Lost Lake” (translate the “Lost Lake”). A significant nickname since each year, in spring, the lake disappears in a hole giving way to a vast meadow.
It is in the National Forest of Willamette, one of the largest forests in the United States, in the state of Oregon, that this mysterious "lost lake" is found which every spring empties like a sink in a hole, before reappearing in winter
A whole underground network which therefore fills with all the water from the "lost lake", which has the effect of feeding the water sources as well as the vegetation of the forest. As soon as winter comes, the opposite effect occurs and the lake fills up again, the ground rejecting all the rainwater that it could not absorb. "The water supply exceeds the speed of drainage," comments Jude McHugh.
In order to prevent the lake from emptying, some anonymous people tried to fill the opening illegally, using various debris such as old engines or car parts. Of course, these actions are condemned by the authorities, a risk of flooding of neighboring roads existing.
