River Description

Quick Facts:
Location: SE Wisconsin, just south of downtown Port Washington.
Character: Tiny, intimate, super-micro-creek; twisting, turning, brush dodging, rock slamming, and virtually guaranteed deadfall and strainer issues.
Shuttle Length/DriveTIme: 0.5 miles/2 minutes. (See details in "Directions" Tab.)

Put-in elevation is approximately 640'.
Take-out elevation is approximately 600'.
Thus total elevation change is approximately 40'.

Drainage area at put-in    : 1.4 square miles
Drainage area at take-out: 2.8 square miles

Information (latitude, longitude, elevations, total drop, run length, shuttle length) all obtained from best extrapolation of data via the distance measuring tool from google.com/maps, USGS StreamStats, and other online resources.

IMPORTANT NOTE: Other sources may show differing values. All values should be merely for general comparative purposes. Relatively minor differences (even discrepancies up to 10-20% and more!) generally mean very little in the grand scheme of all things whitewater! Far more important than gradient and class/rating should be other less-quantifiable 'character factors' such as continuous versus pool/drop, wide-open routes versus constricted technical rapids, wide-channel with multiple routes versus narrow channel with essentially one route, gradual river banks versus rocky shores or steep-walled gorges, et cetera.
Never rely solely on class/rating to decide if you should run a river/rapids!

General Overview

A tiny, intimate 'stupid boater tricks' run with likely snags, 'clothes-lining' deadfall, and tight maneuvering. With a drainage area of no more than 1-2 square miles, obviously this will require significant rain (and/or snow melt) and will have a very short 'window of opportunity'. However, high-water debris I have seen on numerous occasions suggests that it should happen with some (relative) frequency (a few times a year).

Scroll down to the "Rapids" for (slightly) more details why anyone might even look at this stream. In truth, it is recommended as little more than a 'fantasy run'. However, in the event anyone actually decides to run it, scout as much as possible before putting on! Walk the banks through Oakland Avenue Green (Park) from S.Ravine Street to Oakland Avenue, to be aware of what you are getting into!

A stream this narrow, with such vertical banks, will have virtually no eddies and plenty of strainers and sweepers to mess you up. At 'boatable' levels, even this little creek will have powerful forces of flow which could kill you if you are pinned against an obstacle and end up getting flipped under. So, while the actual rapids contain absolutely nothing which exceeds class II-II+, the boater skill-level to successfully negotiate this twisty intimate (and likely snag-filled) stream is much more in the class III-IV range!

Most emphatically, this is NOT something to try in a vinyl raft, air mattress, inner tube! You can almost certainly count on having it popped, or at the least being ejected from it as it wraps or pins on some obstruction. Just as emphatically, this is not a stream for a regular canoe or 'recreational' kayak (with no spray deck). You will not be able to maneuver such a relatively long craft in this narrow creek, your craft will filll with water and you will have a tough time retrieving it from the flow. Even worse, if you end up in the water, and are downstream of your craft, you could easily get pinned and crushed up against a tree or obstruction by your own boat! (This does not discount the possibility that someone might be able to successfully make it down in such a craft, but such success is far more likely a stroke of luck than evidence of actual boating skill.)

Note: DO NOT go beyond the listed take-out. The stream splits just before it gets to the power plant. The left (north) 'natural channel' encounters numerous hazards (significant plant growth, impassably low pipes spanning the stream, a low bridge and other obstructions). There is an 'overflow' channel (which can appear more as the main channel) proceeding along the south of the power plant building. Entrance into this channel is completely blocked by railings affixed atop a short cement diversion wall. This channel is lined with large quarry rock which will take substantial flow to cover sufficiently for passage by canoe/kayak. There are no likely features (other than what may exist as the flow hits the lake). All property around the power plant is posted against unauthorized access (trespass) other than a new lake access south of the power plant. As a result, we cannot recommend proceeding beyond the listed take-out at S.Division Street.

Rapid Descriptions

Upstream of S.Ravine Street

Class - N/A Mile - -0.1
The creek could be theoretically boatable upstream of S.Ravine Street were it not for the fact that the banks are significantly wooded and are subject to erosion. There is so much deadfall blocking numerous locations that only a glutton for punishment would ever try!

Drainage Area: 1.4-2.8 square miles

Class - N/A Mile - 0

I suspect this little creek has a name (almost everything does!), but I have checked numerous maps to no avail. (I have not talked to any locals to see if they know of a name for it.)

Drainage area at Sunset Road/CTH.CC is 1.42 square miles (as calculated by USGS StreamStats 4.0 Beta software). At Ravine Street it has increased to a whopping 2.74 square miles.

Former Dam Location

Class - II Mile - 0.3

A 5' dam used to exist at this location on this tiny creek. As of winter/early-spring 2017 it has been removed, the streambanks 'armored' with large boulders (to stabilize and reduce erosion of the banks which had been disturbed and somewhat denuded to facilitate removal), eliminating the likely main reason to have ever bothered with this tiny creek.

Downstream, as the creek narrows, be ready to encounter a myriad of snags and sweepers to contend with as best you can. Again, this section must be walked to scout thoroughly before even thinking about putting on in any watercraft!

Oakland Avenue (old post-pile)

Class - II+ Mile - 0.4

As the creek approaches the W.Oakland Avenue road bridge, there had been rows of posts anchored into the streambed (undoubtedly remnants of the supports for a long defunct horse-and-carriage bridge). They may have been cut off more recently. However, this area is still very much subject to strainers and snags. So, while any rapids here may technically may rate nothing more than a class I-II rating, the high potential for danger and difficult maneuvering suggest a much higher skill-level may be required than should ever be used to describe the rapids and their class/rating.

Scout this entire run before putting onto the creek!

No Good Choices!

Class - N/A Mile - 0.7
Rapid Thumbnail Missing

The creek approaches the WE Energies Port Washington Powerplant. They have made accommodations for the creek to split here (at times of higher flows).

The (more-or-less) historic channel heads to the left, and is quite narrow and filled with cattails and shrubbery, making passage difficult-to-impossible. In addition, prior to the confluence with Sauk Creek, there are very low-slung horizontal pipes spanning the creek at a height which would confound and completely preclude safe passage.


The second alternative (from the split) would be to the right. WE Energies has created an overflow channel to better accommodate peaking flows. Their property is all posted against 'Unauthorized Personnel'. The overflow spills over a cement wall. Part of this wall has railings which block droping into the channel below, but in recent years (ca.2018/2019) the railing has been removed in the center of this drop. Rocky rubble lines the whole channel down to the lake. Having enough water to make boating this area possible is likely to be far too much water to make the bash-and-crash (down the narrow, strainer-and-sweeper filled main portion of the run) anything close to sane or do-able!

For this reason, exiting the creek before this point is virtually mandatory!

If interested, you should be able to do a 'virtual scout' of this area if you go to Google.com/maps, search for "Port Washington", and zoom into this area.


Gage Descriptions

With a drainage area of no more than 1-2 square miles, obviously this will require significant rain and/or snowmelt, and will have a very short 'window of opportunity'. However, high-water debris I have seen on numerous occasions suggests that it does happen with some (relative) frequency (I.E., a few times a year).

Directions Description

As mentioned in the description, we most strongly recommend walking (scouting) this entire (short) reach before even thinking about running it. Since it is rather short, it is entirely likely that anyone who does decide to actually boat this absurdly small creek is likely to just walk their shuttle.

You may wish to use the text-entry box below to input your home or other starting address to get drive time, distance, and directions to this reach. (It will accept zipcode, as stated, or a full address: street city state, or lat/lng coordinates, ....)
