The Brazos River, its many tributaries and the reservoirs in the Brazos River Authority
water supply system are dynamic and their flow rates and levels can change at any given
time. For those living on or near surface water in the Brazos basin as well as those
wishing to enjoy the recreational aspects of the rivers and reservoirs, up to the minute
information can be not just important but vital.
The River and Reservoir Levels page is being replaced by BrazosBasinNOW, a water information
site that features an interactive map with data provided by several organizations including
the U.S. Geological Survey (USGS) from 59 gages located at points throughout the Brazos
basin. The data typically is collected every 15 minutes and is accompanied by the
conservation and flood pool elevations as well as flood stage elevation, when available.
The information can be viewed in graph or table format. In many cases, historic information
is available. The stream gages record flow rates in cubic feet per second, and the gage
height, which USGS uses to calculate the flow rate. Gage height is not an indication of
water depth at each location.
In the event of flooding, you can also turn to this section for prompt information about
current flood conditions for several gages sites along the Brazos and its tributaries.
You can also find predictions for when flood stages could be reached and when the water
is expected to crest. For current gate releases at B.R.A. reservoirs, see the home page’s
