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
