PROJECT ALERT NOTICE (OK TX) Minor to Moderate Flooding across Texas and southern Oklahoma

Date: Tue, 04 May 2021 10:50:24 EDT

Summary: Widespread rain across much of Texas and southeast Oklahoma has caused minor to moderate flooding

A slow moving low pressure system has led to an ongoing storm event starting Thursday April 29th and continuing through today. These storms have resulted in widespread rainfall amounts of 5 to 8 inches across much of Texas and into southern Oklahoma, with isolated areas in Central Texas and along the Gulf Coast exceeding 10 inches.

At the beginning of the event drought conditions existed over a large part of Texas. Because of this, many rivers have responded but have only been in minor to moderate flood conditions.

No peaks of record have occurred and no gages have been damaged.

During the event, up to ten 2-person crews have been deployed from the Lubbock, Fort Worth, Austin, San Antonio, San Angelo, and Houston offices. Approximately 75 mid-range and high-flow discharge measurements have been made, while approximately 20 water-quality samples have been collected. These activities are continuing today and may continue in some level of effort for the rest of the week. No indirect measurements are anticipated.

USGS has been in contact with various local, state, and federal partners through the event.
