Was up there in Fremont on Monday. We managed a 3-man limit of eyes, one under 15", the rest 15-20. All in the river. Got em fishing deeper water on the outside of bends in the river. Water was around 10-15ft deep in all three areas we got fish. Drifting with the current along the outside bend vertical jigging with a jig and minnow or jig and plastics. The jig and plastic produced the first couple fish, and then everything else came on a jig and minnow, and they wouldn't touch the plastics. Water temps were 52-54, if I remember correctly. Jig color didn't seem to matter as much as keeping it down there within 4-6 inches of the bottom. This was done with 1/4oz jigs. Took 8 hours, but we got the limit, plus a handful of bonus whites(didn't target them), and some huge redhorse that got chucked back into the river.
Bite seemed to go good from about 7-11am, then slowed down, then picked back up around 1-2:30pm. By 3pm it was pretty much dead. We picked up our last one right around 3pm after half a dozen passes with not even a bite, after getting bit by at least some kind of fish on just about every other pass throughout the day.
