Been over to that area a couple of times this week. Used both the Osceola landing and Franconia landings. Still getting my 17′ Navigator through over there. Water still up about a foot from normal summer time lows but plan to run plenty of shallow water. 2 to 3′ is very common with pushing through some spots. Dont think you can get a boat up past the bridge at Taylors falls. Rapids there.
If you are looking for deeper water there is cliffs and a 45 foot hole at Rock Island right above Franconia landing. Wisc. side across from Osceola landing has a decent stretch of 8 to 10′ or water. Down towards the train bridge is another a couple more deeper spots. Did notice some sturgeon jumping down that way the other day. To me just about anything deeper than 3′ or near 3′ of water on this stretch is fishable. Throw is some wood and current and fish may use it.
Dont run on plane unless you know this part of the river. Sand bars come up fast and shallow. Ran my prop in plenty of sand this week and over the occasional log.
Have fun. Great stretch of river to learn .
