More rain is on the way Thursday morning that could add to the flooding.

HOUSTON — The rain from Sunday night into Monday morning is over, but the runoff continues downstream. And more rain is expected Thursday morning.

A Flood Warning for the Trinity River in Liberty County continues as water continues to be released from the Lake Livingston dam. The river is expected to crest on Saturday, reaching a level it hasn’t seen since 1994.

We’re keeping an eye on the bodies of water across Southeast Texas as we watch for potential flooding. 

On Tuesday, a little after 3 p.m., the City of Houston put out an update.

Lake Houston

We’ll start with Lake Houston.  According to the city, the lake is at 43.30 feet, which is nearly a foot over where it is normally. Water is being released from the lake until it returns to its normal level.

People who have property along the lake should secure their property to the shoreline. The water level is expected to continue to rise.  You can monitor Lake Houston levels here.

Lake Conroe

Looking at Lake Conroe, as of 3 p.m. Tuesday, the lake was at 202.61 feet. The normal level is 201 feet. If you want to keep tabs on Lake Conroe levels, you can do that here.

East fork of San Jacinto River

According to the City of Houston, the river is going to rise between 10 and 15 feet from its level on Tuesday at FM 1485 and FM 2090. Major flooding is happening now and will continue Tuesday night into Wednesday in the area, which is in southeast Montgomery County and northeast Harris County.  

High water in Cleveland will go downstream to the Plum Grove area in southeast Montgomery County and the FM 1485 area of NE Harris County.

These are the locations that can expect widespread flooding along the river with several streets impacted in Harris County:

  • FM 1485 will be under several feet of water and be impassable
  • Flows may approach the deck of the HWY 99 bridge over the river

Flooding will happen in the low-lying and underdeveloped areas of Kingwood that back up to the east fork of the San Jacinto River. Flooding into structures isn’t expected.

The west fork of the San Jacinto River isn’t expected to reach flood stage at U.S. 59.

More heavy rain is expected Thursday morning in some of the heaviest hit areas, so you’ll want to download the KHOU 11 mobile app for alerts.
