As long as programs like IDO do shows and put a map up of the area, people will make the connection. All the sloughs and and associated back waters have a limited abaility to replenish themselves. Each year you get some high water and fish disperse to all points on the river. Water goes down and there it is. PDC is a large area compared to most but it can still take a beating. Nelson alma Merrick are all examples of this.
Stay safe out there guys
