Trinity River salmon fishing guide Dave Jacobs June 8, 2015 Recent Catches Trinity River salmon fishing guide. There has been some very good schools of Spring king salmon moving through the Klamath River in May and early June as reported by Trinity River salmon fishing guide Dave Jacobs. The Spring king salmon are now moving up the Trinity River here in early June. River releases are still high on the Trinity but dropping everyday right now. June and early July look to be good times to go after King salmon until the Sacramento River opens on July 16th.
