Description

After the river passes under Highway 41, it loops back to the north bank (river right).  The channel remains against this bank for a ways till it is constricted at this riffle. 

At typical low flows the river narrows down against the right bank.   A tree fell across the river and was cut off, leaving several feet of tree trunk protruding across the current, hence the name.  The high flows of 2011 removed the stump completely.  Now this is an easy and clean riffle that curves to the left. 

Below this, the river widens a bit, passes two smaller riffles then flattens out into a series of large lakes.  The lakes are old gravel mining pits.
