Here are the Monday evening lake and weather numbers for the Lake Houston area. No flood alerts are active for Harris, Montgomery or Liberty counties, and both lakes are sitting within their normal operating range.
Lake Levels at a Glance
| Lake | Level | Percent Full | Reading |
|---|---|---|---|
| Lake Houston | 42.39 feet | 100.0 percent | 5:30 p.m. Central, Monday, October 5 |
| Lake Conroe | 199.90 feet | 94.8 percent | Daily value for Monday, October 5 |
Lake Houston
Lake Houston read 42.39 feet at 5:30 p.m. Central on Monday, October 5, at the U.S. Geological Survey gauge at Lk Houston nr Sheldon, TX, site number 08072000. Over the past 48 hours the lake ranged from a high of 42.80 feet at 11:15 p.m. Saturday, October 3, down to 42.39 feet this afternoon, a spread of about four tenths of a foot. This evening’s reading is the low point of that window, so the lake has been easing down steadily since Saturday night rather than rising.
The Texas Water Development Board puts Lake Houston at 42.54 feet and 100.0 percent of conservation capacity for October 5. That is about fifteen hundredths of a foot above the USGS figure, a wider gap than the hundredth or so the two agencies normally differ by. The USGS gauge remains the source for the elevation figure here, and both numbers are given rather than quietly picking one. The 100.0 percent reading is the fourth consecutive day at that mark, and it means the reservoir is full at its normal operating pool, not that it is in flood.
Lake Conroe
Lake Conroe stood at 199.90 feet and 94.8 percent full in the Texas Water Development Board daily value for Monday, October 5. That is down about two hundredths of a foot from 199.92 feet and 94.9 percent on Sunday, October 4. The figure is a once daily value rather than an intraday reading.
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.
