With the marginal reports and info I fished the Buckhorn bridge and worked down the Yellow river channel to the Wisconsin river channel then up to Devils island. Water temps were 40 degrees at the bridge and decreased down to 36 degrees on Castle Rock. No fish caught down river from the bridge nor many marks on the graph. At the bridge lots of fish hitting on both plastics and jig and minnow. Lots of shorts but several legal and some slots caught. Good luck had by boats and shore fishing guys alike. Castle Rock is low, waters edge is the drop off on the west side. Devils island is a high point on a peninsula, you can walk to it from the normal shoreline. Neat trip, the alumajet is great for exploring those shallow waters.
