MATAGORDA, Texas – It was a shocking sight about 100 miles south of Houston: thousands of dead fish in Matagorda.
A Channel 2 viewer sent us the video. Cody McCarty says the video was recorded off a balcony of a home overlooking the Colorado River.
You can see the dead fish floating in the water.
Another video shows another vantage point. A man who calls himself the "fish whisperer" posted it on his YouTube channel, and it's been viewed more than 400,000 times since Saturday.

We contacted the Texas Department of Parks and Wildlife, asking what might have caused the massive fish kill.
Officials there said they are looking into it, but so far, they do not know the cause.
