Saturday morning on Lake Houston. There are no flood watches, warnings or advisories in effect for Harris, Montgomery or Liberty counties, and both lakes are sitting where they have been all week. The only figure worth a second look this weekend is Sunday’s heat index, forecast as high as 101.
Lake Levels at a Glance
| Lake | Level | Percent full | Reading |
|---|---|---|---|
| Lake Houston | 42.40 feet | 100.0 percent | 5:30 a.m. Central, Saturday, September 19 |
| Lake Conroe | 199.78 feet | 94.3 percent | Daily value for Saturday, September 19 |
Lake Houston
The U.S. Geological Survey gauge at Lk Houston nr Sheldon, TX, site 08072000, read 42.40 feet at 5:30 a.m. Central on Saturday, September 19. Over the previous 48 hours the lake ran between 42.33 feet, recorded at 3:15 p.m. Friday, and 42.45 feet, recorded at 4:15 a.m. Friday, a swing of about an inch and a half.
The Texas Water Development Board lists Lake Houston at 100.0 percent of its conservation capacity for September 19, with its own daily reading of 42.39 feet against the USGS figure of 42.40. That is the normal level of agreement between the two.
Lake Conroe
The Texas Water Development Board daily value for Lake Conroe on September 19 is 199.78 feet and 94.3 percent full, down 0.03 feet from 199.81 feet on September 18. The lake has now eased down for eight days running, a slow decline rather than a drawdown.
Lake Conroe belongs in a Lake Houston paper because the two are connected. San Jacinto River Authority releases from Lake Conroe flow down the West Fork of the San Jacinto River into Lake Houston, so the upstream level is part of the local flooding picture in Kingwood, Humble and Atascocita.
