Lake Houston

The Texas Water Development Board put Lake Houston at 42.53 feet and 100.0 percent full in its daily value for Saturday, September 12, within 0.01 feet of the USGS reading. The conservation pool is full and the lake is holding steady.
Lake Conroe
The Texas Water Development Board recorded Lake Conroe at 199.91 feet and 94.9 percent full in its daily value for Saturday, September 12, down 0.02 feet from the 199.93 feet recorded the previous day. This is a once daily figure 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. That is why the upstream level matters in Kingwood, Humble and Atascocita, and why this paper carries a Montgomery County reservoir reading alongside the local one.
