MCCLELLAN-KERR ARKANSAS RIVER NAVIGATION SYSTEM
UPDATE ON INCREASED DIFFERENTIALS ON
THE WHITE RIVER ENTRANCE CHANNEL
At 11:00 a.m. on January 31 the tailwater elevation at Norrell Lock and Dam
was 128.60 ft-msl and the headwater elevation at Montgomery Point Lock and
Dam was 124.89 ft-msl, with a differential of 3.71 feet. The White River
Entrance Channel (WREC) differential is forecasted to reach 4.6 feet on
Tuesday, February 4, and falling Mississippi River levels may create a
higher differential before the middle of next week. Higher differentials
are expected to persist until Mississippi River levels increase or White
River flows recede. Mariners are reminded of advised tow restrictions
during increased differentials:
WREC Differential # Barges
2.9 feet or less no restriction
3.0 to 4.4 feet 12 barge down bound restriction
No restriction up bound
4.5 to 5.0 feet 9 barge down bound restriction
No up bound restriction
5.1 to 5.9 feet 4 barge down bound restriction during daylight
2 barge down bound restriction during night
No up bound restriction
Mariners transiting the WREC should use extreme caution in this area,
especially when passing Montgomery Point Lock and Dam. Contact Montgomery
Point Lock and Dam or Norrell Lock and Dam for current differential and
elevations or visit our website at
