Good morning. It is Tuesday, September 29. There are no National Weather Service alerts in effect for Harris, Montgomery or Liberty counties this morning. Both lakes are in their normal range, and the Lake Houston gauge has moved less than two tenths of a foot over the past 48 hours.
| Lake | Level | Percent full | Reading |
|---|---|---|---|
| Lake Houston | 42.22 feet | 98.6 percent | 5:30 a.m. Central, Tuesday, September 29 |
| Lake Conroe | 199.55 feet | 93.2 percent | Daily value for Tuesday, September 29 |
Lake Houston
The U.S. Geological Survey gauge at Lk Houston nr Sheldon, TX, site number 08072000, read 42.22 feet at 5:30 a.m. Central on Tuesday, September 29. Over the past 48 hours the gauge has ranged from a low of 42.13 feet to a high of 42.29 feet, a spread of 0.16 feet. The Texas Water Development Board puts Lake Houston at 98.6 percent of its conservation capacity.
Lake Conroe
The Texas Water Development Board lists Lake Conroe at 199.55 feet and 93.2 percent full for Tuesday, September 29. That is down from 199.57 feet and 93.3 percent on Monday, a drop of about two hundredths of a foot. The lake has eased down slowly for several days.
Lake Conroe matters here because San Jacinto River Authority releases from Conroe flow down the West Fork of the San Jacinto River into Lake Houston. What happens on the upstream lake reaches Kingwood, Humble and Atascocita a few hours later, which is why this post carries both readings.
