I believe it is a program that is meant to replace the older Snider Cr program that was discontinued. Here's a blurb from the OPGA site: http://www.olympicpeninsulaguidesassociation.com/events.html

"Broodstock Program

Many of the area's guides and businesses, as well as many of our clients, have played a very important role on an enhancement project that was based on a tributary to the upper Sol Duc named Snider Creek. With this broodstock program, between 50,000 to 100,000 smolt were planted using wild steelhead, rather than returning hatchery fish for the parent stock of the young. The Snider Creek Project became an important part of the rebuilding and continued maintenance of the early-run native Steelhead stocks on the Sol Duc River. When the Sol Duc river was deemed a "wild steelhead gene bank" river in 2012 the Snider Creek program was relocated to the Bogachiel and we are working on building it back up."

Not sure about the details of operation.
