It was a sight to be seen - or maybe not seen.

When emergency crews arrived at El Dorado Lake Wednesday, they couldn't see the two vehicles they would be working with because both were underwater.

A two-ton dump truck and large trailer rolled into the lake around 1 p.m. Wednesday. They were being used to pull a large boat out of the lake. Neither got far before being submerged in water.

The driver was able to crawl out a window without injury.

A tow truck arrived on the scene about four hours later and was able to pull the trailer and dump truck from the water.
