Mother's Day Caddis has bloomed and depending where you are on the system will dictate your day. Every day and zone has been different, as Caddis tend to be a more complex hatch. We have seen zones where there were literally thousands and thousands of egg layers and spent Caddis with very few risers, and we have seen some incredible 'rise fests' as well.
Watch for shady zones to be key and if you can't find risers, keep moving till you do. Fish eating Spent Caddis, Emergers and Egg layers can be sporadic in their pattern; at times they can by rhythmic as well.
The river bumped up in flows and lost some clarity a couple days back but everything has stabilized recently and we are good to go.
