Rainbow trout set for early release in Lake Siskiyou Staff reports This year’s crop of Alaska-quality rainbow trout at Lake Siskiyou will be released a month early, the last week of April, announced Mt. Shasta Rotary in a joint statement with the California Department of Fish and Wildlife. The early release will provide the chance at a world-class catch while the surface waters are still cool in May and early June, said Tom Stienstra, president-elect for Mt. Shasta Rotary and director of the Rotary trout pens. “By setting our big Rotary trout free a month early, it will provide a sensational local opportunity before the campgrounds fill up,” Stienstra said.
