If you are to go on the second trip and need to book your week soon, You should most likely do it for any time after july 20th. THe river is most likely to be in decent shape then.
The tackle shops to call and try to get decent info from are the following, Misty river, Nortcoast Anglers and Fishtales. All three are in terrace and some one should be able to supply you with decent info. I would contact them in the order I have listed them. If you fish any plugs there are a few things to know about. Only one single barbless hook allowed and you can not fish sardine wrapped kwikfish. We are not allowed to use any bait fish when fishing salmon or steelhead , only sturgeon. You can you pro cure or smelly jelly products on your plugs instead.
