Humboldt Open Ocean Dredged Site (HOODS)
The HOODS was established as a permanent ocean dredged material disposal site in 1995 for Humboldt Bay and the north coast of California. It was used by the Corps of Engineers as an interim site beginning in the fall of 1990.
Prior to 1990, disposal occurred closer to the Humboldt Bay entrance channel, but concerns about mounding of material at that location affecting waves (and possibly the safety of vessels leaving and entering the Bay) led EPA to establish the new site in deeper water farther from the Bay entrance channel.
