UPDATE ON INCREASED DIFFERENTIALS ON
THE WHITE RIVER ENTRANCE CHANNEL
MCCLELLAN-KERR ARKANSAS RIVER NAVIGATION SYSTEM
This is to advise mariners
transiting the White River Entrance Channel (WREC) of increased head
differentials between Norrell Lock and Dam and Montgomery Point Lock and
Dam. At 7:00 a.m. today, the tailwater
elevation at Norrell Lock and Dam was 143.41 ft-msl and the headwater elevation
at Montgomery Point Lock and Dam was 140.97 ft-msl with a differential of 2.44
feet. Due to a rapidly falling
Mississippi River the WREC differential is forecasted to increase to 3.0 feet
by Friday, February 19th and is expected to remain above 3 feet for about 7
days. Mariners are reminded of advised
tow restrictions during increased differentials:
