Lake Conroe Exceeds Full Level; SJRA Beginning Controlled Releases

With an average of 1.7 inches of rainfall across the watershed in the last 24-hours, the Lake Conroe water level has risen above the normal pool elevation of 201′ above mean sea level (msl). Around 12:30pm, SJRA operations personnel at the Lake Conroe dam began controlled releases to slowly pass a portion of the inflows coming into the lake. The current release rate is 1,059 cubic feet per second (cfs).
Throughout this entire storm event, information regarding lake level and releases will be sent, in real-time, to SJRA’s core partners, including Montgomery County, Montgomery County Office of Homeland Security and Emergency Management, City of Houston, Harris County, Harris County Office of Homeland Security and Emergency Management, Harris County Flood Control District, National Weather Service, Coastal Water Authority, etc.
Depending on the rate and amount of additional rainfall, the lake will continue to slowly rise, and releases will be adjusted accordingly. The operational guidelines for Lake Conroe are designed to ensure that the peak rate of flow released from the dam is LOWER than the peak flow coming into the lake.
Since it is difficult to accurately predict how far the lake will ultimately rise, Lake Conroe personnel will continue actively monitoring the storm and communicating with local officials.
