A public comment period for the U.S. Army Corps of Engineers Grays Harbor Navigation Improvement Project draft limited reevaluation report including a draft supplemental Environmental Impact Statement has been extended through April 8.
The Corps investigated the feasibility of dredging the channel from the South Reach upstream to Cow Point to its fully legislatively authorized depth of -38 feet MLLW. This project covers approximately 14.5 miles of the 27.5 mile channel.
The Grays Harbor federal navigation deep draft channel is 250 feet wide at Cosmopolis, increasing to 1,000 feet over the Bar at the mouth of Grays Harbor.
The currently maintained channel depth is -36 feet Mean Lower Low Water (MLLW) from the South Reach to the Cow Point Reach, where Port of Grays Harbor Terminal 4 is located.
