I've spent the last three afternoons playing around on the Lower Sac with friends and family.  I confirmed that you can indeed catch fish on the Lower Sac without using a bobber.  On Monday night I did really well side-drifting nymphs from the boat.  That was a lot of fun because you feel the grab and you're tight to the fish right away.  On Tuesday we did a lot of wading.  Scott Saiki caught some nice fish high-sticking while wading and from the anchored boat.  The highlight was last night when I caught four nice trout on my 5wt spey rod.

 

There are a lot of caddis around right now so Fox poopahs and natural bird's nests are working well.  There is a good baetis hatch in the last hour, too.
