ROCKWALL (CBSDFW.COM) – At least 21 families have evacuated from flooded homes along a swollen Lake Rockwall.

Guadalupe Vazquez filled her car with her most valuable possessions on Thursday night, including pictures of her late mother and her children when they were young. “We need to get everything that’s irreplaceable,” said her son, Luis Landaverde. “We can get clothes whenever we want, but pictures of the past, we have to get those first.”

“It’s scary because, if it starts raining tonight, if we fall asleep, we’re not going to know,” said Landaverde on Thursday.

A few houses down, 14-year-old Kaylene Delgado was packing a bag with clothes in case her family needs to leave. Her parents have been cleaning up water that has already crept into the back door. “It’s actually been rising,” she said. The family hopes to stay,but want to be sure that they are not left stranded. “It’s kind of hard to get out with all the water.”

The neighborhood has been barricaded to make sure that nobody is allowed inside. But no one has been forced to leave.

Residents said that they are used to the lake level rising after heavy storms, but they have never seen anything like this before, where the water reached into homes. “We just thought it was going to be okay,” said Stephanie Lomas. “My father-in-law said it’s never this bad.”

The situation is not expected to get much better on Friday, and more thunderstorms are in the weather forecast for Saturday morning. The Rockwall Police Department has stationed several officers in the area to watch over the homes and the families who have chosen to stay behind. Those who have been displaced were able to get hotel vouchers from a county agency.
