Preheat oven to 350. Drain salmon, reserving liquid. Discard skin, but save bones. Flake salmon lightly, but well, with a fork. Crush bones and mix with the salmon.
Add the lemon to the reserved salmon liquid and enough cold water to make 1/2 cup liquid; add to the salmon. Add all remaining ingredients and mix thoroughly. Form into 4 patties. Bake for 25 to 30 minutes.
