Lake Conroe, Bayou, and Creek Update
MONTGOMERY COUNTY, TX -- Intense rainfall rates of 3-5 inches per hour are moving into the Kingwood, Humble, Huffman, Crosby, Atascocita, Highlands, and Mont Belvieu areas. This will result in rapid onset flash flooding in urban areas, overbank flooding, and near bankfull conditions across Northeast Harris County, Liberty County, and Southeast Montgomery County early today.
Lake Conroe is currently at 199.02 feet above mean sea level (msl), which is two feet below normal pool elevation of 201 feet. The Lake Conroe watershed has averaged just over one inch of rainfall in the past 24 hours, so all Lake Conroe dam gates remain closed and no water is being released.
San Jacinto River Authority (SJRA) continues to coordinate with numerous operational partners to include: Harris County Flood Control District (HCFCD), Harris County Office of Homeland Security, Montgomery County Office of Homeland Security and Emergency Management, and Emergency Management, National Weather Service, and the River Forecast Center.
Harris County's bayous, creeks and tributaries are continuing to respond to the runoff from heavy rainfall. Several bayous are near the top of banks, while San Jacinto and Cedar Bayou have overtopped their banks. An update on bayous and creeks that HCFCD officials are watching closely (as of 9:30 a.m.):
The following are out of banks:
• East Fork San Jacinto at FM1485
• East Fork San Jacinto at FM 2090
