If you put in above the 1st Crossing bridge, be cautious of the pilings from the old bridge, which are located just downstream of the current bridge. These form about 20 slots across the river. At high dam releases (thousands of cfs), some of these slots can form grabby hydraulics and/or collect large debris (tree limbs, etc.) Generally the second slot from the left is the best one to take, assuming it isn't clogged with debris. The river left side of the bridge also has the most vertical clearance.
