Yep, that's the plan by the powers that be.
The only thing open to dredging are waters that have no fish passage, ie, a dam with no fish ladder, or a waterfall that they can't get over.
Now that they have that, and all 303d listed waters closed, they're after to the rest. They'll get that in the next few years.
On the permit application you have to list GPS coordinates, down to three decimal points, using their map. Now they know how many permits are in each area. Next step is to start with the most popular spot and figure out a reason to close it.....like they did last year out of Cottage Grove. They made mention of Quartzville, so I expect that's next on the list. Can still use up to 4" there, in season.
Unless you have the permit, prepare for sticker shock. And have heard of people getting billed for the next year, even if not planning on renewing, and sent to collections if not paid.
