Brazos River Information

The Brazos River rises and falls due to the amount of rainfall upstream of the District within the Brazos River watershed.  When significant rainfall occurs upstream, the National Weather Service will issue forecasts for the Brazos River to alert residents of anticipated conditions so that informed decisions can be made related to potential impacts from rising water. The nearest river gauge and forecast site is the Brazos River at Richmond, at the US 90A bridge, approximately 8.8 miles upriver from the I-69/US 59 crossing. The forecast estimates the level of the river at the gauge, the level provided is in gauge feet (not feet above sea level).  To convert gauge feet to sea level add 27.02’.  Because LID 17 is downstream from the gauge, the water level in the Brazos River will be lower than at the gauge, generally about 6-7’.  The Districts’ consultants monitor the river levels and forecasts.  When necessary, the District responds, per the Emergency Action Plan, with required activities to protect the District and properties therein from potential harm.  For reference;

  • A gauge elevation at the Richmond gauge of 37 would correlate to gravity outfall being restricted at Pump Station 2 (south of UH) such that pumping operations might be required if there is rainfall within the District.
  • A gauge elevation at the Richmond gauge of 43 would correlate to gravity outfall being restricted at Pump Station 1 (north of I-69/US59) and pumping operations might be required if there is rainfall within the District.
  • On September 1, 2017, following Hurricane Harvey the Brazos River crested at a high of 55.19’

Brazos River Levels

Residents-

Due to rainfall upstream of the District in the Brazos River watershed, we are anticipating elevated water levels in the Brazos River and Ditch H. The current forecast is estimating the Brazos River level at the Richmond gauge to be 39.2 feet on Sunday, October 21, 2018. It is possible we could see Richmond gauge at or above 40 feet. For your reference, the Brazos River crested at 55.19 feet during Hurricane Harvey. The District’s operator and engineer are monitoring and will continue to monitor the Brazos River levels and update the District’s website as necessary.
