Suction dredge mining could be permanently banned from Western Oregon’s wild salmon habitat under a bill that has passed the Oregon House.
The bill creating stream protection passed Wednesday and is awaiting Gov. Kate Brown’s pledged signature, The Mail Tribune reported (http://bit.ly/2qG9NS5 ).
Suction dredging uses floating vacuums to suck gravel from a stream bottoms. Material vacuumed by the dredges then go through sluices so miners can strain out gold and other heavy metals. Sand, silt and other fine material are discharged into the water.
Wild-salmon advocates say the process damages spawning grounds and rearing habitat. Miners have argued current laws already protect salmon habitat and that no peer-reviewed study on suction dredging proves it ruins salmon habitats exists.
The bill would make permanent 2016’s temporary ban on suction dredging within creeks and rivers deemed “essential salmon habitat.” The bill also bans dredging in habitat of Pacific lamprey, which are also present in the Rogue Basin.
In 2013, the Legislature passed a bill detailing new dredging restrictions, capping the number of dredging permits offered annually in Oregon and limiting some of the times, locations and manner for how dredgers operate. It was designed to expire at the end of 2015 to give the Legislature time to grapple with permanent rules, which are now on the horizon.
