Generally too low to call it whitewater; It is possible to paddle flatwater pools, but gradient/shoals will be grungy scrape.
As the river reaches the Johnson Dog Walk Park, it bends left (east) and then right (south and west). Through this whole area, current increases, and a fine series of swifts, riffles, and rips exist at moderate flows. At lower flows, expect to grunge out on shoals.
Proceed with caution at high flows, since you will have less time to avoid any snags that might lie in wait around these bends! (Paddle hard away from downed trees, as you are likely to be pressed into them and flipped.)
