Description

Visible from a footbridge spanning the cement ditch at 8th Street (which dead-ends on each side of the river), this hydraulic jump is quite interesting. As shown in the photo, the right side stays high further than the left side. All faces are sloped rather than vertical, making for some VERY interesting currents here.

Also, immediately at the base of the drop, on the left, there is an storm sewer (combined sewer) outlet which could (at times of excessive rains) contribute significant contaminated flows.

Anyone considering putting in upstream of this point should stop here first to have a look at this feature. At flows around 300-400, left-of-center has a wicked looking wrapping wave, while the right-side drops into a fairly significant reversal. It will take significant skills to avoid being violently flipped by the strong currents! (A 'power nasal flush' of stormwater is likely to ensue.)
