I had posted this earlier as the Second largest hole in a lake. However as per the latest information received by me it is Fourth largest. I have therefore merged this post in a combined post which now includes all the large "Hole in A Lake"

World's Fourth Largest Hole in a Lake
The strange looking hole in the lake is actually an uncontrolled type of spillway to control the level of the Lake created by a dam. Such holes are called morning glory, plughole, glory hole, or bell-mouth spillways.
This spillway located in lake Berryessa , Monticello Dam, California is Fourth largest glory hole in the World.

ReplyDeleteNot as large as the two at Ladybower reservoir in the UK, both 80 feet in diameter with a drop of around 200 feet, discharging into the river Derwent
ReplyDeleteThank you Anonymous for the information. I stand corrected. My information was based on several web pages which I found in Google search.
ReplyDeleteI am making a separate post about Ladybower Lake's overflow holes and will be giving due credit to you.
Thanks once again.
