Lake Levels at a Glance
| Lake | Level | Percent full | Reading |
|---|---|---|---|
| Lake Houston | 42.16 feet | 98.6 percent | 5:30 p.m. Central, Tuesday, September 29 |
| Lake Conroe | 199.55 feet | 93.2 percent | Daily value, Tuesday, September 29 |
Lake Houston
Lake Houston read 42.16 feet at 5:30 p.m. Central on Tuesday, September 29, on the United States Geological Survey gauge at Lk Houston nr Sheldon, TX, site 08072000. Over the previous 48 hours the gauge ranged from 42.11 feet to 42.25 feet, a swing of about an inch and a half.
The Texas Water Development Board puts the reservoir at 98.6 percent of its conservation capacity on its daily value for September 29, with the board’s own elevation reading at 42.22 feet. The small difference between the two numbers is the normal gap between an intraday gauge reading and a once-daily reservoir value.
Lake Conroe
Lake Conroe stood at 199.55 feet and 93.2 percent full on the Texas Water Development Board daily value for September 29, down from 199.57 feet and 93.3 percent on Monday. That is a decline of about a quarter of an inch in a day, which is an ordinary late-September drawdown rather than a release event.
San Jacinto River Authority releases from Lake Conroe flow down the West Fork of the San Jacinto River into Lake Houston, which is why the upstream level matters to residents of Kingwood, Humble and Atascocita.
