(Portland, OR) -- The Oregon State Marine Board is banning loud personal watercraft from a section of the Willamette River. The board approved a temporary rule that limits personal watercraft to 75 decibels from the shoreline between Willamette Falls and the Waverly Marina. The rule is needed to stop the repetitive use of personal watercraft through that section of the river, because of complaints from homeowners. The Marine Board is working on a permanent solution to the problem.
