rip fyi if you bring a spinner to yellowstone the only real place to fish is on Yellowstone Lake. is impossible to fish with one anywhere else there is so much moss in those rivers.
edit: they are tring to get rid of the lake trout, which somehow got into yellow lake, heart lake, and shone lake. heart lake is the best place to fish for them if you want to take the hike up a mountain and down. you can catch as many as you want and keep them all. No possession limit.
Yellowstone lake. All lake trout must be killed. either keep them or puncture air bladder.
shosone is regular limits.
lake trout also usually live down deep. around 50-600 feet and they are usually bigger than 20 inches.
