Lake Houston
The U.S. Geological Survey gauge at Lake Houston near Sheldon, site 08072000, read 42.26 feet at 5:30 a.m. Central on Friday, September 25. The Texas Water Development Board puts the reservoir at 99.2 percent full.
Over the past 48 hours the gauge has stayed within about one tenth of a foot, ranging from a low of 42.24 feet at 2:45 p.m. Thursday to a high of 42.37 feet at 11:30 a.m. Wednesday. That is a flat stretch with no rain moving through the watershed.
Lake Conroe
The Texas Water Development Board lists Lake Conroe at 199.66 feet and 93.7 percent full on Friday, September 25, down two hundredths of a foot from 199.68 feet on Thursday. The lake has been easing downward for more than a week.
Lake Conroe matters in Kingwood, Humble and Atascocita because San Jacinto River Authority releases from Lake Conroe flow down the West Fork of the San Jacinto River into Lake Houston. What the upstream reservoir does eventually arrives here.
