Lake Houston and Lake Conroe had their water levels lowered ahead of Tropical Storm Nicholas’ anticipated effect on the Greater Houston area.
Just after 2 p.m. Sept. 13, the San Jacinto River Authority, which manages Lake Conroe’s water levels, reported on its website that the lake was approximately 1 foot below conservation pool. The river authority tweeted that it anticipated 4-10 inches of rainfall from Nicholas.
(1/2) TS Nicholas is expected to bring 4”-8” inches of rainfall north of I-10. #LakeConroe is currently over a foot below conservation pool, allowing significant space to capture potential rainfall and runoff from the storm. No water releases at this time... pic.twitter.com/LLaTj5IbP6
