About this graph

Tabular Data (UTC)

Tabular Data (CDT)

Datum: NAVD88

Metadata

NOTE: The reference level, or vertical datum, for this gage has been updated to NAVD88. That means the stage heights will now be reported from that reference level which will give the water level as height above mean sea level. All flood stages have been changed accordingly.

NOTE: Automated gauge readings are now available, courtesy of the USGS.

Reliability of the Forecast: Based on current and forecast river, weather and reservoir conditions

NOTE: Forecasts for the Angelina River near Lufkin are issued as needed during times of high water, but are not routinely available.

Vertical Datum updated from NGVD29 to NAVD88 by gauge owner.

Flood Impacts & Photos

179	Major flooding including water across the southbound lane of U.S. Highway 59. Expect high water to continue on the lower Angelina River to above Lake Sam Rayburn for several weeks, with flooding of several thousands of acres.
178	Expect major flooding including water across the northbound lane of U.S. Highway 59. One can expect high water to continue on the lower Angelina River to above Lake Sam Rayburn to continue for several weeks with several thousands of acres flooded.
177	Expect moderate flooding to continue for several more days with seasonal high water and minor flooding to continue for several more weeks as the lower Angelina River above Lake Sam Rayburn slowly recedes.
175	Moderate flooding to continue for several weeks on the lower Angelina River to above Lake Sam Rayburn with several thousands of acres flooded. High water begins to fill the ditches of both the northbound and southbound lanes of U.S. Highway 59 to approaching near the emergency lane shoulders.
171	Expect moderate flooding with the gravel access roadway completely flooded. High water approaches the tops of the cement support piers on the U.S. Highway 59 bridge with boat traffic under the bridge becoming very difficult with very little clearance. Also expect flooding to continue for several weeks on the lower Angelina River to above Lake Sam Rayburn.
170	Expect minor flooding to continue for several more days, as the Angelina River above Lake Sam Rayburn slowly recedes.
168	Expect flooding to continue for at least a couple of weeks with the gravel access roadway nearly inundated along its entire length.
165	Expect flooding to continue for several days with the majority of the gravel access roadway flooded. Boaters and four wheel-operators should use caution traversing both upstream and downstream on the Angelina River as currents can become swift and turbulent.
162	Minor lowland to diminish and end on the lower Angelina River.
161	Expect minor flooding with the gravel parking lot flooded and water beginning to overflow the gravel road where it widens into the parking lot. Also expect about a foot of overflow across the left bank of the Angelina River looking downstream.
160	Action stage with overflow into the gravel parking lot for boats and trucks on the right bank. Also overflow just begins on the left bank side looking downstream on the Angelina River. Expect overflow into the majority of the gravel parking lot.
158.5	Bankfull stage for the right bank of the Angelina River looking downstream. Expect minor overflow into the very edge of the gravel parking lot for boats and trucks.

Additional Information

During periods of possible very heavy rainfall, river forecasts may take into account precipitation amounts expected 30, 36, or even 48 hours into the future from the forecast issuance time. Please note the recent datum change to 0.00 feet using the North American Vertical Datum of 1988. The former zero gauge datum before 2022 used 164.72 feet using National Geodetic Vertical Datum of 1929.
