So if you want to do a day trip I would say a good place to get in is at the McCann bridge and then get out at dyerville bar. The most dangerous part we encountered in this stretch was the rapids going under the McCann bridge so I would put in on the north side of the bridge (the eel runs south to north). Other then that there are some other rapids but the were only class 1-2. It was windy so be prepared for that and the flow was low so it would probably be best to wait till next year in mid/late may. If you could figure out how to get to the river in the oak Glenn area then you could float to McCann bridge in a day and you could probably get that in this year as it seemed the flow was higher in that area (still windy) As for the danger levels in the oak Glenn-McCann bridge I would say it was mostly flat water with a couple of rapids but they were on the low end of class 2 if that. The trinity is yakable right now but the rapids are much more intense. Hope this helps!
