Good evening from the Lake Houston area. No National Weather Service alerts are active for Harris, Montgomery or Liberty counties this evening, and both Lake Houston and Lake Conroe are sitting in their normal range.
Lake Levels at a Glance
| Lake | Level | Percent full | Reading |
|---|---|---|---|
| Lake Houston | 42.35 feet | 100.0 percent | 5:30 p.m. Central, Friday, September 18 |

Lake Houston
The U.S. Geological Survey gauge at Lk Houston nr Sheldon, TX, site number 08072000, read 42.35 feet at 5:30 p.m. Central on Friday, September 18. Over the previous 48 hours the lake ran between 42.33 feet, recorded at 3:15 p.m. Friday, and 42.46 feet, recorded at 1:00 a.m. Thursday. That is a swing of about an inch and a half.
The Texas Water Development Board lists Lake Houston at 100.0 percent of conservation capacity for September 18, with its own elevation reading of 42.40 feet. That is the normal level of agreement between the two sources.
Lake Conroe
The Texas Water Development Board daily value puts Lake Conroe at 199.82 feet and 94.5 percent full for Friday, September 18, down one hundredth of a foot from 199.83 feet on Thursday. The lake has edged down every day for a week.
Lake Conroe belongs in a Lake Houston paper because San Jacinto River Authority releases from Lake Conroe flow down the West Fork of the San Jacinto River into Lake Houston. What happens upstream is part of the flooding picture in Kingwood, Humble and Atascocita.
