As I mentioned at the very end of the previous chapter, the most important key to be successful at the Lower Slough Creek is to spot and observe trout (on top of possessing right flies and proper skills and understanding hatches). The character of flows is one of a kind: it's so slow that trout can cruise anywhere to feed, even during hatch periods. Consequently they can rise to top from any directions unlike typical trout in typical streams that usually face and feed at the upstream direction. But it's still a flow that is very enough to cause drag on our leaders and flies. That's why I tell people "Lower Slough is the toughest public spring creek in the world!!"
