TRWD staff continues to monitor conditions in the TRWD reservoir watersheds 24 hours a day.  Graphic-1 below shows the past 24 hours of rainfall across TRWD reservoir watersheds.  Light to moderate rainfall is expected to continue overnight, with possible rainfall depths between 0.5”-1”.  The metroplex and part of the Eagle Mountain watershed will remain under a Flood Watch until 7 AM tomorrow morning, with possible localized rainfall depths of 1-2”.  For the latest weather updates follow the latest National Weather Service (NWS).

River levels at the West Fork Trinity River Jacksboro and Boyd gage sites have crested for the time being.  The Jacksboro gage is still within the Action Stage as defined by NWS River Forecast Center; however, the Boyd gage has fallen below this threshold.  Use the linked names to follow the latest at these sites.

In the Richland-Chambers area, the Trinity River at Trinidad is currently in Minor Flood Stage and projected to reach Moderate Flood Stage by Saturday.  Chambers Creek near Rice is currently increasing, and about to cross the threshold between Moderate and Major Flood Stage.  Use the links to access the latest forecast information from the River Forecast Center for these sites.
