Beginning Sunday fluctuations in the pool behind the New Savannah Lock and Dam will occur and last approximately two weeks.
The changes in water level will occur to enable data collection connected to a geotechnical investigation on the lock and dam structure.
All fluctuations will remain within the normal operational range, which is between 112 and 115 above mean sea level (ft-msl).
Throughout the data collection process there will be a drill rig and work boats just upstream of the lock and dam site.
Boaters are urged to use caution in surrounding areas and when using the boat ramp upstream of the lock and dam.
The water level will re-stabilize at its normal level, about 114 ft-msl, when the work is complete.
Today, Jan. 3, the level at the lock and dam is 114.2 ft-msl.
