PROJECT ALERT NOTICE (TX) Flooding in North Texas

Date: Tue, 23 Aug 2022 12:10:33 EDT

Summary: Flooding from significant rainfall over the past several days is occurring in several areas of Texas, with the most severe in the Dallas/Fort Worth Metropolitan Area

While rainfall has fallen across much of Texas since this past weekend, the Dallas Fort Worth area has received significant rainfall amounts over the past two days. Widespread 2-day totals range from 3 to 8 inches, with some areas receiving a record amount of just over 9 inches in a 24 hour period. This has resulted in flooding in the urban areas as well as tributaries to the Trinity River.

The NWS is forecasting additional rain for the rest of the week and with everything saturated, runoff and more flood issues are expected. The focus for widespread heavy/significant rainfall is sagging to the south of the DFW metroplex. High water is possible in the Sabine, Neches, and Angelina Rivers, while the existing flooding is in the Trinity River basin and may result in minor river flooding along the mainstem as the water moves downstream towards the gulf coast.

Currently, 2 sites on the Trinity River are above minor flood stage. Yesterday, discharge measurements were made at 4 streamgages by 8 members of the North Texas Branch Office. Measurements are being made today at an additional 4 streamgages. No streamgages have been damaged during the event and no indirect measurements are expected.

USGS staff have been in contact with local cooperators, as well as the Corps of Engineers and the National Weather Service.
