--trout aggressively feed on salmon eggs so fly or plastic egg imitations work well this time of year.
--many fish the mouth of the Adam's as large trout from shuswap gather at the mouth to feed on eggs washing down.
--also resident Adam's river trout feed on eggs plus imitations of the salmon as they develop over the year.. so egg&eye, Alvin etc. as the year progresses.
--I expect wherever there is a consentration of salmon spawning other species will be aggressively feeding on eggs and even salmon flesh imitations ... so kinda match the hatch type of fishing.. we often change the colour of eggs and flesh fly patterns as the feed changes from bright orange, pink, red eggs to washed out white grey flesh patterns.
--egg colour changes getting lighter the longer they stay in the water so we use light purple, or washed out colours of pink red and glow white.
--light gear... just be prepared to break off if you hook a salmon although expect in many areas to be getting larger trout as well so be prepared and gear up accordingly
