One non-flood alert is active: an Air Quality Alert covering Harris County, which runs through 8 p.m. tonight. Both lakes are in their normal range.
Lake Levels at a Glance
| Lake | Level | Percent Full | Reading |

Lake Houston
The U.S. Geological Survey gauge at Lake Houston near Sheldon, site number 08072000, read 42.14 feet at 5:30 p.m. Central on Monday, September 28. Over the previous 48 hours the gauge ranged from 42.13 feet to 42.29 feet across 190 readings, from 6:15 p.m. Saturday to the latest value. The lake is down about 0.06 feet across that window, a slow decline rather than a rise. The Texas Water Development Board puts Lake Houston at 98.5 percent of conservation capacity for Monday.
Lake Conroe
The Texas Water Development Board reported Lake Conroe at 199.58 feet and 93.4 percent full for Monday, September 28. That is down 0.02 feet from 199.60 feet on Sunday, continuing the gradual decline of the past several days. This is a once daily value, not an intraday reading.
Lake Conroe matters in Kingwood, Humble and Atascocita because San Jacinto River Authority releases from Conroe flow down the West Fork of the San Jacinto River and into Lake Houston. When the upstream lake rises and the authority opens its gates, the water arrives here.
