Description

After 43rd Street, the river passes under a pedestrian bridge and turns sharply to the left (to head north for a short distance) before encountering a railroad embankment where it again turns to the east. Anyone foolhardy enough to be in the river is advised to get out and scout before rounding that bend.

Almost immediately around the bend is about a 5.5' vertical corrugated-iron-wall drop. River-left of the landing pool, two culverts under the railroad contribute flow of "43rd Street Ditch" (a 2.3 sq.mi. tributary, nearly equal the KK at this point), which may cause some interesting currents at times of high flow.

It looks like it could be fun just to carry in to run this drop ('doing laps'), but with such tiny drainage area, getting here when it has the right flow would be exceedingly rare. However (having looked at this once at relatively high flows), flow 'backwaters' so much here that the pool height nearly eliminates all of the drop! So, you'd need 'goldilocks' flows: enough water to not totally scrape coming into/over the edge, but not so much water that the pool height all but eliminates the drop.

While we have seen no specific plans, it seems likely this 'jump' will be removed as part of the MMSD projects affecting both the KK and the 43rd Street Ditch.
