From the National Weather Service - West Gulf River Forecast Center on the upcoming rainfall event
Bottom line – Forecasted rainfall and associated runoff for the upper portion of the Brazos River watershed upstream of PK down to Lake Granbury will likely cause increases in release rates at both reservoir projects over the next several days.
The release at Lake Granbury was reduced down to about 2,200 cfs a short time ago, but as additional rain enters the watershed later today and into tomorrow increases to the release rate are likely.
We continue to release approximately 680 cfs through the 78” ring-jet-valve at PK and will increase the release as inflows into the reservoir increase.
Water Services will continue close coordination with all three reservoir projects and other Central Office staff as this rainfall event unfolds.
If you are downstream, please remain aware.
Rain is expected to fall on already saturated soils causing additional runoff focusing primarily from Lake Granbury upstream through PK over the next 36 to 48 hours. Wednesday night presents the possibility of some severe weather and locally heavy rain. Rainfall amounts of 1 to 3 inches with locally higher amounts are expected over the Flash Flood Watch area through Wednesday evening.
The focus of the system then will shift southeastward late Wednesday through Friday targeting more of the central portion of the basin including Lake Limestone.
