River Description


Quick Facts:

Location: Downtown Grafton to south of town.
Shuttle Length: 1.5 miles/6 minutes. (See details in "Directions" Tab.)
Character: Rocky shoals and swiftwater lead to a wide bedrock slide (Falls Road Ledge). Another brief paddle leads to a smaller bedrock intrusion (Lime Kiln Park Ledge).

Put-in is approximately 725' elevation. (Per scan of GoogleEarth data.)
Take-out (Lime Kiln Park Canoe Landing) is just about right at the 690' elevation contour line on topo maps.
Thus elevation change is approximately 35'.

Video: https://youtu.be/fMx9dsjahQc <<< The first 2:34 of this video offers highlights of this run. The remainder of the video shows fine highlights of a run on the very nearby Cedar Creek.

General Overview
At lower water levels (below about 500 cfs), this run may be suitable for beginner/novice paddlers as a whitewater trip and scenic paddle.
At moderate to higher levels (~700-1300 cfs and beyond), the run offers a fine handful of interesting play options (for those at least mildly experienced in whitewater).
At levels of ~1200-2000 cfs, experienced playboaters will likely focus on PnP at Lime Kiln Park Ledge (LKPL).

The removal of two dams (January, 2001: "Chair Factory Dam", just upstream of Falls Road, and winter of 2010/2011: Lime Kiln Park Dam) has improved boating opportunities on this stretch of river. No significant rapids were revealed with either removal -- only some minor shoals and tame waves, as well as a couple great squirt spots (relatively well-defined eddylines with good depth). (Watch for these where the flow is deflected off of rock walls.)

It is importaint for novice boaters (and not a bad idea even for experienced boaters) to  scout the Falls Road ledges before putting on upstream, to know whether you feel comfortable running them at the water level you have when you are there. Portage (for downstream bypass, or carry-up for re-run or park-and-play) at this location IS NOT LEGAL! (See more details in the Rapids" description for "Falls Road Ledge."

While you are scouting this ledge, take a little time to read the signage in the greenspace (mini-park) at the corner of Falls Road and S.Green Bay Road  to learn some local history. Originally the Wisconsin Chair Company occupied this site (powered by a dam, now removed). Later, Paramount Records used the buildings as a studio, an important connection in what was known as "The Blues Trail".
 

Rapid Descriptions

Bridge Street Dam

Class - N/A Mile - -0.1

The dam at Bridge Street (immediately above our listed put-in) has been a point of significant debate. There is a mandate that all dams must be able to handle a 0.5% chance ('500 year') rain event (flooding). There was discussion about allowing fish passage (as has been done with the dam at Thiensville), but somehow in this instance, it was overridden by concern to keep the dam as the final barrier on the Milwaukee River to spreading of VHS (viral hemorrhagic septicemia) and various possible invasive species. A binding referendum was passed (April 6, 2010) to preserve the Bridge Street dam until at least 2019. The dam has been modified to include a release gate (to regulate flow only at times of high water).

While this dam has been run (as shown in photo), we do not recommend it. At moderate-to-high flows, the boil-line is well out from the dam, and would be difficult to escape. At lower flows (such as pictured), there are reportedly some places where the landing is quite shallow, thus piton potential is problematic.

Put-in; Drainage area: ~470 sq.mi.

Class - N/A Mile - 0

For those (extremely rare) paddlers coming from further upstream and planning to continue downstream, there is a marked portage around the dam on river-right. Whitewater paddlers generally will ignore the signage directing those boaters to a put-in at the south end of this dead-end stretch of 14th Avenue. Our suggested put-in lies just behind the first building (closest to Bridge Street). A paved area sloping down to a glass-craft studio (on the south end of the building) leads to shore areas convenient to put in from. (The proprietors of that business have been quite genial on the few occasions I have chatted with them.)

From this put-in, you have strong currents to contend with (at least, at good boatable flows). Immediately downstream there is a fair-sized island. More of the flow heads to the left of the island, which is usually the preferred (more interesting) route.

1st Squirt Spot

Class - I Mile - 0.1
Rapid Thumbnail Missing

As soon as the large island ends, look for a rock-outcropping on river-left, and catch the eddy behind it. For anyone 'old-school' enough (especially old-school longer boats or squirt boats), this is a great squirt spot. At flows above 800 cfs (perhaps even down to 500 cfs), there is great depth here, and a sharp eddy line for bow-stalls, stern squirts, and whatever other squirt moves your boat and your ability or interests allow.

For beginner boaters, this is a great practice spot. Paddle to the 'top' of the eddy, peel-out into the flow, and charge back into the bottom of the same (river-left) eddy.

There is also a much larger eddy on river-right (with much less-defined eddyline). This allows paddlers to practice ferrying from one eddy to the other. (With bow pointed upstream, trying to move laterally across the flow, losing as little distance downstream as possible! For an added exercise, try doing a 'back ferry': with bow downstream, backpaddling, again trying to move laterally across, losing as little distance as possible!) Another fine practice maneuver is paddling up the eddy, peeling out (angling bow into the current, to then head very briefly downstream), then charging hard for the eddy on the opposite side, paddling up that eddy to do a peel-out and charge back into the original eddy. (I call these "figure-8's".)

Each of the above make excellent practice on dealing with currents and eddies, managing boat angle, changing boat lean, and other essential beginner swiftwater/whitewater skills.

As previously mentioned, there is generally very good depth in the main flow here, so it makes a fine spot to practice rolling (intentionally or otherwise) in current. However, anyone missing a roll and ending up swimming may find it will take some distance downstream to be able to get boat and boater ashore. (There is not significant rapids or danger, just strong currents in a relatively wide section of river.)

Grotto Wall

Class - N/A Mile - 0.3
Rapid Thumbnail Missing

We highly recommend paddling close to shore in areas of high rock-wall 'dells' (mostly on river-left along this stretch of river), to more fully take in their detail, with little caves, nooks and crannies, ferns, moss, and cliff swallows. (Sometimes scenic beauty is best appreciated from a distance, sometimes best up-close and personal!)

 

Minor play wave.

Class - I Mile - 0.46
Rapid Thumbnail Missing

Head over to river-right, charging to right-shore just past a rocky outcropping, to catch an eddy just past a small bit of a wave. Smooth, easy surfs are possible here.

Tame play wave, and 2nd Squirt Spot

Class - I Mile - 0.55
Rapid Thumbnail Missing

OK, there really are at least a few other spots for squirts and minor surfs (depending upon flows). However, the second more significant one will be at river-right, as you pass another rock outcropping on shore, and encounter a couple decent sized rocks in the river (covered but visible around 800 cfs, obviously visible at lower flows, imperceptable at higher flows). A decent shore-eddy allows staging to paddle up toward the rocks, plow the bow (or stern) in just toward center-stream of them and get vertical. There is good depth immediately adjacent to them for stalls and squirts (and rolling if you have to), but there will be some large rocks if you miss your first or second roll attempt.

Falls Road Ledge

Class - II+ Mile - 0.65

A sloping bedrock ledge provides an exciting/wild ride for novice boaters, but only minor potential for whitewater play. Specifically, there are minor play opportunities at low-to-moderate flows (on the order of 200-600 cfs or so). As levels rise, some play may still be possible, but it becomes tough to get repeat play, as eddies are few and current is pushy.

There are a couple different choices of route down this drop (and it's runnable about anywhere with high enough flows). The most usual routes are fairly well to the right (but about 20-30 feet offshore) or well to the left (about 10-15 feet offshore). Either way, some maneuvering and quick reactions and bracing are likely to be necessary as the currents twist and turn off various bedrock and rock-rubble intrusions into the flow from the base of the main ledge and the runout beneath the bridge.

This feature should be scouted before putting on upstream, to be certain of your comfort with running it  (at the water level you have when you are there), since both sides of the river are private residential property with signage against trespass!

If you feel you'll need to portage, you have three options:
A) KEEP YOUR FEET WET! (Not a very good option since there is much rocky rubble (river-right) and slippery bedrock (mainstream and river-left), along with strong currents at best boatable flows.)
NOTE: Many people (both fishermen and boaters) seem unaware that Wisconsin's law was changed many years back to 'keep your feet wet'. If you are on dry land which is not public parkland or officially designated public portage path, you are trespassing!
B) While setting shuttle, knock on one of the doors to ASK permission to (very briefly and most directly) traverse downstream. (If you don't find either owner and get a 'Yes', it's a 'NO!')
C) If you won't/don't do either of the above, you need to skip the upper stretch and put-in either here (downstream of the main drop) or someplace downstream!

Note: there may be some remaining rebar (metal rods) and there is definitely much rock rubble in the river below the old dam site. Numerous large rocks and bedrock splines lie just beneath the surface (especially in areas closest to either shore) and will be brutal on boaters who flip or swim.

Lime Kiln Park Dam (now removed)

Class - I Mile - 1

Passing under Falls Road, a quarter-mile paddle (through uneventful 'bobble water' shoals) brings you to Lime Kiln Park, where you'll see a small rocky prominence just prior to the second former dam-site. Removal of this  relatively short (but classic 'killer' low-head) dam was completed during winter, 2010/2011.

The river is very deep where the dam was (making it a very popular fishing hole). Again, there may be some very decent eddylines with great depth. (Another fine place for a squirt boat or longer 'old-school' playboat, to do bowstalls and sternsquirts, though realistically, the eddylines and opportunities are better in the two spots previously mentioned.)

Immediately downstream, an island will be encountered (likely with a collection of wood broached at its head). The left channel is minor riffles and rips, leading to a slightly undercut wall as the river is diverted to the right to rejoin the other channel.
 

Lime Kiln Park Ledge/Wave (LKPWave)

Class - N/A Mile - 1.06

The right channel (around the aforementioned island) twists right then left, and trips across a short bedrock intrusion ('ledge').

Minor play may be possible as low as perhaps 250 - 1000 cfs, however the river is shallow immediately downstream, and holds many rocks, so any flips or rolls will be brutal in these low ranges. (One local boater suffered a dislocation here and dissuades all he talks with from playboating here!)

As levels head into the 1000-1300 cfs range (on the listed 'virtual gauge') the wave starts to build nicely (though still backed up rather immediately by shallow rock, and the eddy and shape of the wave can make it challenging to regain the wave).

As levels hit the 1300-2000 cfs range (and possibly a bit higher), this is  great for fast, powerful surfs (though seldom, if ever, retentive enough for full-out rodeo moves). I'm not sure at what level (on the high end) it disappears or becomes unplayable, though generally it is washed out above 3000 cfs.

Just downstream, where the currents rejoin (at the end of the small island), depth is generally sufficient for bow-stalls and stern-squirts, as well as fine ferrying and eddy practice for beginners. This makes a fine park-and-play spot (even having warm bathrooms for changing out of the elements), though there is really just the one good wave/hole to play here.

Lime Kiln Park Canoe Landing

Class - N/A Mile - 1.2
Rapid Thumbnail Missing

Downstream, a pleasant bit of riffles leads to the Lime Kiln Park canoe landing (river-right).

This is the recommended put-in for canoes and for less experienced (non-whitewater) kayakers, and our recommended take-out for experienced whitewater boaters interested in just the best of whitewater on this part of the river.

Downstream of this point, while the river is certainly scenic and enjoyable, there is little more than riffles and rips (class I-I+) at virtually all flows.

Grafton Dells

Class - N/A Mile - 1.38
Rapid Thumbnail Missing

Just downstream lies Grafton Dells. This is a fairly scenic and rather popular stretch of river for novice canoe trips. Riffles and rips (depending upon water level) will be found as the river is split by a number of islands. Wildlife is commonly seen while boating this reach (deer, heron, turtles, etc.). Deadfall and strainers may be a problem in one or more channels. For those who do proceed downstream, the recommended take-out is at Hwy.T, since the river becomes increasingly flat and slow below there, containing no additional whitewater or swiftwater.

 

CTH.T/Lakefield Road; Drainage Area: ~472 sq.mi.

Class - N/A Mile - 2.75
Rapid Thumbnail Missing

This is the first available landing for those paddling downstream of the main whitewater stretch, doing the Grafton Dells.

CTH.T is approximately 1.5 miles downstream from the canoe launch/landing, and sits at ~673' elevation. Thus, elevation change from LKP Canoe Landing to there is approximately 17' (Gradient just over 10 FPM, versus the 30 FPM on the listed 1.2 mile whitewater section.)

Confluence w.Cedar Creek

Class - N/A Mile - 3.2
Rapid Thumbnail Missing

Cedar Creek can be a fine 'companion run'. Those looking for the best whitewater action on it take out where it crosses CTH.T, but it could also be continued down to this confluence (and beyond, to next listed access).

CTH.C/Pioneer Road

Class - N/A Mile - 4.5
Rapid Thumbnail Missing

From CTH.T to CTH.C one encounters random rocky shoals interspersed with flat, but well-flowing water.

(For canoeists and recreational kayakers putting in at the Lime Kiln Park launch site, this is 3.3 miles downstream.)

Downstream of CTH.C, the shoals quickly diminish (in length and frequency). The next access point would be another 3 miles downriver at Highland Road (mile 7.5/6.3, not recommended as a take-out, due to general lack of good parking).

Not far beyond, one is pretty much in the backwater of the dam in Thiensville, so current quickly subsides and motor boat traffic may be encountered. (I believe the entire stretch of river is a mandated "Slow, No Wake" zone for them, so you should not encounter water skiers or PWC ('jet skis').)

From Highland to the launch/landing in Thiensville Village Park is another 3.47 miles.

The dam in Thiensville has a fun-looking slide far to river-left, and (at some levels) looks like it could provide some entertainment or play. The center and right part of the dam drop vertically onto shallow rock (at low-to-moderate flow) or into a nasty keeper hydraulic (at moderately high flow). (Interestingly, at super high flows, you'ld never even know the dam was here! Water backs up and totally engulfs the dam!) As of November, 2010, a fish ladder exists on river-right. However, the entire area within 200' of dam is off-limits for boating, the police/fire station is quite nearby (right at the entrance to the park, within sight of the parking area by the dam), and enforcement is reportedly fairly strict.

Ran this stretch on 8/6/11 @240cfs. Scrapped in quite a few areas.

With the removal of the Lime Kiln Park dam, far more boaters are likely to be doing this stretch of river. After passing through the rock outcroppings where the dam once stood, you encounter an island. Trees, branches, and wood of all sorts accumulate at the head of this island. BE CAREFUL not to be swept into that woody debris! (There is one live branch which extends horizontally and low over the left-half of this river-right channel.) We do recommend taking the right channel to get to the Lime Kiln Park Ledge (Wave). If you take the left channel, the large branches broken down from a large tree (which hung into the river-left eddy since March, 2011) have now fallen and flushed downstream.

I found a youtube video of what the area looks like without the dam. http://www.youtube.com/watch?v=eUIo-SywO6w

Gage Descriptions

*The 'virtual gauge' (#7238) subtracts the flow of Cedar Creek (#1875) from the 'Milwaukee@Cedarburg' (#1876) gauge, which is below the confluence, thus giving a much better estimation of the actual flow on this reach.

Using that virtual gauge, the minimum of 200 cfs pretty much represents a level below which much of this run will become scrapey, and very little resembling whitewater will be found. The 'maximum' (1400cfs) is only set as an indicator of levels 'above the norm'. The river is runnable much higher. Playability at Falls Road generally diminishes at levels above 700-800 cfs (due to 'push' -- features will 'flush out', and be difficult to regain). However, the single ledge/wave at Lime Kiln Park becomes more interesting and worthwhile at levels above 800. (I'm not sure at what level it 'washes out' -- it's present and playable to at least 2000 cfs.) For just river-running, there is virtually no 'maximum' for suitably experienced boaters. We are aware of runs of Falls Road at 4500 cfs, when it was a fast flush with monstrous, chaotic waves!

For winter, we revert the gauge to the 'stage' reading of the Milwaukee@Grafton. Min/Max are altered accordingly, and 'bumped up' considerably, to levels which may be expected to blow out enough ice to make (park-and-) play at the Grafton ledges potentially feasible. Obviously, there will be 'false positives', that is, gauge reports of 'runnable' may not be proven correct upon on-site inspection.

Approximate Stage/Gauge Correlation (for winter/'ice'):
6.22' = 350<
6.57' = 600 -- 'winter min'
7.17' =1000
7.95' =1500
8.71' =2000 -- 'winter max'

Looking at it another way, Cedar Creek (at it's gauge, which is admittedly a few miles upstream from the confluence with the Milwaukee) has a drainage of 120 square miles, while the Milwaukee (just downstream of the confluence) has a drainage of 607 square miles. Thus, on average, one could 'subtract out' 1/5 the flow on the Milwaukee at Cedarburg gauge to approximate the flow of the Milwaukee at Grafton, which has been done for the following analysis:

Drainage area at gauge: 480 sq.mi.
Minimum mean daily flow during stated period: 26 cfs (2003.09.05)
90% of time flow exceeds: 78 cfs
10% of time flow exceeds: 720 cfs
Maximum mean daily flow during stated period: 5280 cfs (2008.06.10)
10/90 ratio ('flashy-ness'): 9.23 (under 3 is fairly steady, over 10 is quite 'flashy')
Average days per year over recommended 'low' threshold: 180
Average days per year over recommended 'high' threshold: 30

Directions Description


Those looking for the best whitewater play may forgo the shuttle, and just Park-n-Play at Lime Kiln Park (likely parking in/near the 'roundabout'/cul-de-sac before the roadway drops down to the canoe landing).

Since property on both shores at Falls Road is private property, while you can park and scout that area, you can no longer legally carry up to run (to park-and-play) that drop unless you knock on a door to get permission from each/either property owner.

We will note that the default shuttle below goes out to the main road through town. Far more often, we opt to use 13th Ave, 12th Ave, and S.Green Bay Road, allowing scouting of Falls Road en route.
