Flood Warning System

Flood Warning Information

The City of Fort Worth Flood Warning Information is designed to provide real-time flood warning risk levels, in order to protect people from hazardous flood conditions.

Residents can see real-time flood warning information at monitored low-water road crossings. The Flood Threat link shows whether the road crossing is experiencing no known threat ("NONE"), potential conditions for flooding ("CAUTION"), or has overtopped ("AVOID").

Purposes and Objectives

The flood warning system in Fort Worth, known as the High Water Warning System (HWWS), relies on water level measurements made at 52 low-water crossings throughout the city. Roadside flashers are installed at those 52 locations, to immediately warn drivers of a flood hazard. At the same time, text and email alerts to first responders are issued when the water level sensors of each flasher system are triggered from rising water.

Weather data (mainly rainfall) is collected at 39 low-water crossings and seven other weather stations. The gaged data is communicated through two dedicated radio frequencies in real-time, to a receiver station at the Burnett Plaza building.

The Flood Warning System (FWS) will use the HWWS communication backbone as much as possible, while adding to weather data collection, and will disseminating the real-time data to the public and other stakeholders.

A grant through the Texas Water Development Board (TWDB) provided development support for this system. The grant project had the following overall goals:

  • Improve system reliability
  • Expand the gaging network with additional rain gaging sites
  • Upgrade data collection and data dissemination (communication tool) software
  • Develop a Flood Response Plan

Flood Response Plan


Three public meetings related to the TWDB grant were held on the following dates:

Public Meeting 1: March 23, 2017

Public Meeting 2: Nov. 1, 2017

Public Meeting 3: Dec. 12, 2018


Find data about your address, including if your property falls within a regulatory floodplain or is in an area that is potentially flood prone.
