The Brazos River Authority plans to open one gate at Possum Kingdom Lake's Morris Sheppard Day at noon, Thursday, July 6, 2023, for a total release of 9,600 cfs. The gate is expected to remain open for approximately 18 to 20 hours.
The water released from the gate at PK will take around 35 to 44 hours to travel downstream to the USGS gage near Dennis (about 7 hours upstream of Lake Granbury). The river level along the Brazos River near Dennis, just upstream of the Horseshoe Bend area, will start rising late Friday evening and into early Saturday morning. At this time, flood impacts due to the release from PK are not anticipated along the Brazos River in Palo Pinto, Parker, and Hood counties. Inflows into Lake Granbury will increase Saturday morning as it takes around 2 days for the water to travel the approximate 145 river miles from Morris Sheppard Dam at PK to DeCordova Bend Dam at Lake Granbury.
Lake Granbury’s reservoir elevation was 691.95 ft-mean sea level measured at the USGS gage at DeCordova Bend Dam at 8:15 Thursday morning. The BRA plans to increase the release rate at Lake Granbury sometime Friday to manage the lake level and ensure there is adequate vacant storage in Lake Granbury to receive the water moving downstream from PK. At the conclusion of this inflow event, both PK and Lake Granbury will be full. For additional information, contact the Public Information Office at 888-922-6272 or email us at email@example.com.
