Which river are you going to? You should be able to do it easily and cheaply once there
Just for the record, this year’s catches amount to 1184 fish since June 01st, average weight 7 Ibs, with the best catch a 25 pounder caught on the first week. An average year under difficult weather conditions!
It is always difficult to define the best fishing period for a specific river: For the Mandal river, looking at the years 2015-2019, the weeks giving more than 150 catches are as follows:When I was there we had low water, ~35m3/s dropping to about 20m3/s by the end of the week. There were very few fish climbing the waterfalls, mostly just residents sitting the deeper holes. But saying that, I did catch a 'mellom laks' with sea lice in zone 3 on the first day, so some made it up!
It seems we were too early in the season, I'm sure I'll return though
