Lewisville Lake nears capacity after highest rainfall month since 2015 floods. The last time the spillway flooded was June 2015, which came after a May that saw 16.96 inches of rainfall.

Likewise, how deep is the Lewisville Lake? 20 m
Also question is, how was Lewisville Lake made?
The lake was created by the completion of the dam in 1955 and later renamed Lewisville Lake. Lake Dallas's dam was later breached and the two lakes combined. The dam is 32,888 feet long (over six miles) and is constructed of compacted soil. A 560-foot uncontrolled spillway sits at the eastern end of the dam.
How does a lake dam work?
When the water level reaches the inlet opening, it spills into the pipe and goes out the back of the dam. This controls the level of water in the lake. When there is too much water for the principal spillway to handle, water will flow through the earthen spillway at the end of the dam.
