Location: Greendale (Milwaukee), WI.
Character: Cement ditch, with seven 'hydraulic jumps' (pour-overs, from 12" - 40").
Shuttle Length/Drive-Time: 0.9 miles/3 minutes.
This 'fantasy run' cement ditch drains the Southridge Mall (and immediately surrounding area). At S.76th Street (where it comes out from underground) drainage area is under 1 square mile. Obviously, it will take considerable rain to make any significant flow here, and flow will drop off almost immediately after it stops raining.
Access at the upper end is problematic. Martin Luther High School sits river-left, but their lot is gated and patrolled. Richlonn's Tire Center sits river-right, and would be a better bet for parking, but to keep things proper you'd have to talk to someone there before parking a car in their back lot. (Boaters should never assume it is ok to park without first asking and securing permission, even from businesses and private/church-school property.) The take-out area may also be contested, as a Milwaukee County ordinance (by every possible interpretation I can make) prohibits launch, landing, or 'touching upon the shore' with 'any float, boat, or watercraft' at any spot not designated by the county as a landing spot unless you have written permission from the parks director.
So ... why put it on here? Well, (1) In case some paddler becomes otherwise aware of it and thinks they've discovered an 'unknown' hitherto unrun bit of whitewater (I.E., a 'first descent'), and (2) because it is obvious (from debris lines on shore and in the trees) that it does occasionally get enough water to be runnable, and (3) because In less than a half-mile (after which it flows into the Root River), it has seven hydraulic jumps (cement ledges), with one at just 1', one at ~40", and the rest at ~3'. (NOTE: Heights listed are actual height of cement ledge when dry. With boatable flows, actual height of drop is likely to differ significantly.)
Permits are not required for this reach.
If someone gets hurt on a river, or you read about a whitewater-related injury, please report it to
American Whitewater. Don't worry about multiple submissions from other witnesses, as our safety
editors will turn multiple witness reports into a single unified accident report.
Log into the American Whitewater website and you can contribute to river descriptions,
flow and access tips, and maps associated with runs you've done. You can even add new
runs to the inventory!
