Navigation Regulations

The U.S. Army Corps of Engineers is proposing to amend the regulations which establish restricted areas at Bonneville Lock and Dam, at McNary Lock and Dam, at Ice Harbor Lock and Dam, at Lower Monumental Lock and Dam, at Little Goose Lock and Dam, and at Lower Granite Lock and Dam on the Columbia and Snake Rivers, Oregon and Washington. The Corps is making adjustments in the restricted area boundaries to provide a greater margin of vessel safety from sudden dangerous currents, turbulence, and whirlpools caused by the operation of spillways, electrical generators, and navigation locks. Vessels, except Government vessels, are prohibited within the restricted areas. The restricted areas upstream and downstream from the spillways can be extremely dangerous should vessels be in the restricted area when water is released. The operation of electrical generators and spillway gates are remotely controlled from Portland and not operated by personnel at the facility. The equipment can be activated within seconds, creating very dangerous water currents, turbulence, and whirlpools. Operation of the navigation lock also creates a very dangerous condition in the downstream area. Water that is dis
