Monday evening in the Lake Houston area. There are no active National Weather Service flood alerts for Harris, Montgomery or Liberty counties, and both Lake Houston and Lake Conroe are sitting in their normal range.
Lake levels at a glance
| Lake | Level | Percent full | Reading time |
|---|---|---|---|
| Lake Houston | 42.11 feet | 97.7 percent | 5:30 p.m. Central, Monday, October 19 |

Lake Houston
The U.S. Geological Survey gauge at Lk Houston nr Sheldon, TX, site number 08072000, read 42.11 feet at 5:30 p.m. Central on Monday, October 19. Over the preceding 48 hours the gauge recorded 190 readings and ranged from 42.06 feet to 42.17 feet, a spread of about an eighth of a foot. The lake has been close to flat all day, with the last six readings sitting between 42.10 and 42.13 feet.
The percent full figure above comes from the Texas Water Development Board daily value for Lake Houston, which put the reservoir at 97.7 percent on Monday. The board’s own elevation reading for the same day is 42.11 feet, matching the USGS gauge exactly. The elevation reported here is the USGS figure.
Lake Conroe
Lake Conroe stood at 199.55 feet and 93.2 percent full on the Texas Water Development Board daily value for Monday, October 19. That is down two hundredths of a foot from Monday’s reading of 199.57 feet and 93.3 percent on October 18, continuing a slow decline that has run through the past week. This is a once daily value rather than an intraday reading, so it carries no timestamp.
Lake Conroe belongs in a Lake Houston paper because San Jacinto River Authority releases from Conroe flow down the West Fork of the San Jacinto River and into Lake Houston. The upstream level is part of the local flooding picture in Kingwood, Humble and Atascocita, which is why this page carries both lakes rather than one.
