This is the Legendary Sockeye Salmon location in the Grizzlies West at Lake Isabella.
Recommended Lure: Special Lake Lure
Stand on the ice in the middle of Lake Isabella and cast facing south east. Slowly reel in the lake lure. You don't need to cast near ripples, the Legendary Sockeye Salmon will swim towards the lure from far away. You can see the ripple in the water as it swims towards your lure.
If your line breaks try casting closer to the edge of the ice so you have less distance to reel in the salmon.
