Federal Flood Risk Reduction Project – Clear Creek

The Clear Creek Federal Flood Damage Reduction Project is a partnership project between the U.S. Army Corps of Engineers, the Harris County Flood Control District, Galveston County, and Brazoria Drainage District No. 4.  As of the June 2019 Project Partnership Agreement between the Corps and the Harris County Flood Control District, the Flood Control District is the lead agency for this project, under a non-federal implementation pilot program authorized by Section 1043(b) of the Water Resources Reform and Development Act (WRRDA) of 2014.

The portion of this project within the limits of Brazoria Drainage District No. 4 is Clear Creek between SH 288 and Dixie Farm Road and Mary’s Creek from Harkey Road to SH 35.

Flood Warning System

Harris County Flood Warning System

In 2018 Brazoria Drainage District No. 4, through the use of a Memorandum of Understanding (MOU) with the City of Pearland and an Inter-local agreement with the Harris County Flood Control District, installed 8 new rain/storm gauges throughout the district (map of gauge locations).

The purpose of this project was to remove the old gauges that the City of Pearland owned and replace them with the newest technology in order to give residents within our jurisdiction real-time monitoring of our local streams and bayous.  The data includes water levels, rainfall amount, historical flooding data, a visual cross-section of the associated drainage channel, and our benchmark information at each gauge station.

When it begins to rain, data-collecting sensors at each gauge station transmit rainfall amounts via radio frequency every time 0.04 inches of rain is measured by the sensor. Sensors that transmit bayou/stream levels report every 0.10 foot rise in water levels.  The sensors transmit information to four primary repeaters located in the Huffman, Clodine, League City, and Tomball areas.The repeaters then relay the data to primary and back-up base stations located at Houston Transtar and at the Harris County Appraisal District. The information is monitored daily by software and by Flood Control District staff to ensure the gauges are properly functioning and transmitting accurate data.

Update: We have are in the process of adding 8 new locations around our District.  Check out the latest map and get live updates via text or email at the Harris County Flood Warning System site:
