Myself and three companions are heading to Iliamna for a fly-out DIY river float from June 17-23rd. Our dates and starting point in Iliamna are finalized. Now we are trying to decide on which river? The Stuyahok or the Koktuli? We are most interested in the trout, grayling, and char fishing. We will not be targeting the Kings. We are experienced boatmen but would prefer to focus on the fishing and not technical boating. Any recommendations on which river might offer the best experience this time of year? Are there any other rivers out of Iliamna we should be considering for a 7-day float? Is the record snowfall this winter having an impact on the river flows? Thanks in advance for your input.
