We fished the delta from sun up til one, in the area around the SJ and Franks. We caught many dinks. We did end up catching five in the 3.5 to 5.5 lb. range. Not great but certainly a pretty day. The bulk of the big school fish aren't in yet. I thought about a five wt. with a small clouser (maybe a size 2), you could have a blast. You could catch a dink 8-14" on every cast.
