I'm not sure about the lake, but up in Kodiak you always had to watch the tide. Durring both ebb and the flood, watching for the fish to make big loops around the bays and casting to the pod.
The Alaskan fish also seemed to like brighter and brighter fly's the closer they got to making their run. Clouser Minnows at the beginning and allot of rabbit strips and flash towards the end.
Good luck and get allot of backing!
