Buffalo Bayou Gages Downstream of Houston Area Reservoirs, Addicks and Barker

The flooding downstream of Addicks and Barker reservoirs due to Hurricane Harvey can be seen in the Buffalo Bayou gages below these reservoirs.

Three gages are shown in this post.  From upstream to downstream, these gages are:

• Buffalo Bayou at W Belt Dr, Houston, TX
• Buffalo Bayou at Piney Point, TX 
• Buffalo Bayou at Houston, TX

The locations of these gages are shown in the figure below.  The gages are shown with the yellow thumbtacks (you may need to scroll to the right to see all of the gages).  Data for these gages was derived from the USGS website.

Buffalo Bayou at W Belt Drive

The figures for the gage, Buffalo Bayou at W Belt Drive are shown below.  This gage shows about a 33 foot rise in about two days due to the rainfall from Hurricane Harvey.

The flow at this location peaked at about 20,000 cfs.  It falls slowly due to releases from Addicks and Barker reservoirs.

The gage recorded over 30 inches of rainfall in about four days.

Buffalo Bayou at Piney Point

This gage experienced about a 35 foot rise in about two days.

The flow is falling slowly due to Addicks and Barker releases.

Buffalo Bayou at Houston

This gage rose about 35 feet in about three days.  The gage height fell about 13 feet from its peak and recedes slowly due to Addicks and Barker releases.
