As images of flooded highways, airport runways and neighborhoods spread out of Houston, one thing has become clear. Amid the catastrophic and historic rainfall totals, Texans with the ability to help their fellow citizens are turning themselves into rescue teams as rescue professionals find themselves overwhelmed.

A Harris County official asked members of the public who have a boat or a high water vehicle to help with efforts to rescue Houston residents whose homes have flooded in the torrential rains brought by Tropical Storm Harvey.

Many have responded.

Harris County Judge Ed Emmett said at a news conference Sunday that the additional boats and vehicles that Texas is sending to the Houston area are not able to get to the area due to flooded roadways, per the Associated Press.

From kayaks to hover-boats, locals with the resources to help others have been doing what they can.

Here is a collection of those in and around Houston lending a helping hand.
