In the midst of what is now officially the wettest October in DFW history, Lewisville Lake is almost filled to the brim.

The lake is at its highest level since January 2016, and could be poised to flood down the spillway. The last time the spillway flooded was June 2015, which came after a May that saw 16.96 inches of rainfall. This October has seen 14.33 inches of rainfall as of last night Oct. 24, according to the U.S. National Weather Service of Fort Worth. That makes it the wettest October on record for DFW with another week to go.

As of this writing, Lewisville Lake is at 529.47 feet above sea level with the flood pool 72 percent full, according to the U.S. Army Corps of Engineers tracking website. At 532 feet, water will begin to go over the dam’s spillway.

The lake’s volume is divided into separate pools based on elevation. Below 522 feet above sea level is the conservation pool, which the Corps tries to keep full. This is the water the city draws on for drinking and municipal use.

Above 522 feet is the flood pool. When the lake is above 522 feet, the Corps will release water from the dam’s outletworks. to get it back to 522 feet — but the Corps will only do this if the Elm Fork of the Trinity River can handle the discharge without causing other flooding downstream. That’s why, in order to release the water, these rains need to stop.

According to The Weather Channel’s website, they may do just that. The next six days show between a 0 and 10 percent chance of precipitation and temperatures mostly ranging from the low 50’s to low 80’s. However, the forecast for Oct. 31 shows scattered thunderstorms with a 60 percent chance of precipitation. Several days of early November show between 40 and 60 percent chances of rainfall as well.
