I fished Hathaway last summer, and this past weekend was up at Deka and Sulphurous. Only managed one kokanee in Deka. There are lots of lakers and bows to be had in Hathaway (Sulphurous is across the road and a great option as well!). We use lead core line and adjust our depth accordingly. I find that Kokanee king, Dick nite, and even small croc's seem to produce pretty well. The lakers are really aggressive up there. Last year we caught a burbot in early September on a dark cloudy day, wish I knew more about them at the time. I did find there are lots of pikeminnow in the shallows but when you get to the deep end of Hathaway you'll find a healthy population of Lakers; rainbows tend to be a little closer to the surface, 15-30 feet down. Best of luck, don't get caught out there in a storm!
