Blackhawk Island



Date Paddled: May 29th, 2010
Put-in: 28th Ave - Mile North of Upham Woods
Take-out: 28th Ave - Mile North of Upham Woods
Distance: 2.5 Miles
Time: 90 Minutes (estimate)
Gradient: 1.4' per Mile
Water Level: Wisconsin River @ Wisconsin Dells 3950 CFS (good depth)

A very nice trip in and of itself is the Blackhawk Island loop. It’s about 2.5 miles and the current isn’t too bad. The west side is protected from the big boats because it is relatively shallow (although private boats/jet skies can be a nuisance on the northwest side). The east side is the main channel but because this has been made no-wake this is relatively kayak-friendly as well.

Blackhawk Island itself is like a good chunk of the Wisconsin Dells in that it is publicly owned but largely set aside for exclusive use by private companies and private organizations (in this case run by and for 4-H, which is pseudo-public). So while the island has a cool trail system and boat access on the southwest side, it is not open to the public without approval from either the DNR or Upham Woods 4-H.

The parameter of the island is quite cool to kayak around though. Put in at the west landing (it’s a pull-off…but nice) and head upstream. There will be cool bluffs on the right… When you get to the fork at the top of the island end don’t go downstream just yet but explore the two gulches on the east side or the east channel…very scenic (but tour boats go in here, so be careful). After the gulches end, go downstream to the bottom of the island, then upstream around the south end of the island to complete the loop.

Webmaster’s Update – 2016:

The Blackhawk Island landing now has no-tresspassing signs and is no longer an option.  For a list of alternate landings, see the overview map below.

Webmaster’s Update – 2020

Four years ago, UW Extension shut down a key landing on the Upper Dells located at Blackhawk Island because of “safety” concerns. To this day the landing is still not available to the public…but a new “paddle pass” program has been implemented. If you pay five dollars, take an orientation class, and check in at the main office beforehand…then you can put in or take out here.

Quick Overview

  • Upstream of Wisconsin Rapids:  I don't have information yet on these stretches.
  • Biron to Lake Petenwell:  ~27 miles.  This stretch in Central Wisconsin used to have many natural rapids, but most have been buried under 5 dams, some of which are now difficult portages.  Despite this there are still some good paddling to be had in this region.
  • Lake Petenwell:  14.9 miles.  This is a large lake that is challenging for paddlers because of frequent strong winds and big waves.
  • Castle Rock Lake:  14.5 miles.  Another large lake that is likely too big for enjoyable paddling.
  • Castle Rock Lake Dam to Lemonweir River:  9.4 miles.  This pre-Dells leg isn't elite, but is a pleasant stretch.
  • Lemonweir River to Indian Trails Landing:  21.7 miles.  This includes the famous Upper Dells and Lower Dells which feature many scenic sandstone outcrops.
  • Indian Trails Landing to Portage:  16 miles.  This is an overlooked section sandwiched between the Dells and Portage.  While the scenery isn't top-notch, it does have many sandbars and few people which is a nice combination.
  • Portage to Lake Wisconsin:  14.3 miles.  This is a neat stretch of the river with many sandbars and cliffs, but the shoreline is very developed and motorboat traffic can be heavy on weekends.
  • Lake Wisconsin:  14.5 miles.  This is a challenging lake for paddling because of its huge waves created by motorboats.
  • Prairie du Sac Dam to Port Andrews:  57 miles.  This is the first half of the famous Lower Wisconsin.  This is a super popular stretch for paddlers with the highlights being large sandbars, big bluffs, occasional cliffs, and fun side sloughs to explore.
  • Port Andrews to Wyalusing:  40 miles.   This is the second half of the Lower Wisconsin which has far fewer paddlers and sandbars.  But the bluffs and sloughs are larger and more interesting.

Detailed Overview

  • Upstream of Biron:  I don't have information yet on these stretches.
  • Biron Dam North Gate to Veteran's Memorial Park:  4.5 miles.
    • Biron Dam North Gate to Biron Landing:  1.0 miles.  Super scenic stretch by two islands with many granite boulders.
    • Biron Landing to Legion Park:  3.0 miles.  A nice stretch by Big Island.  The west channel is more undeveloped...but the east channel has several scenic granite islands.
    • Portage through Legion Park:  680'.  A steep wall separates the park from the river but in two locations the wall is short enough to get over (see map).  Paddlers may want to consider a longer portage to bypass some of the shallow rocky stretches by Legion Park.
    • Legion Park to Veteran's Memorial Park:  0.4 miles.  A scenic stretch that features a large boulder field and the powerhouse of a large paper mill.
  • Veteran's Memorial Park to Port Edwards Landing:  3.8 miles
    • Veteran's Memorial Park to Demitz Park:  0.8 miles.  A pleasant stretch that includes Belle Island.
    • Demitz Park to Ben Hansen Park:  1.2 miles.  This leg goes by Garrison Island and Edwards Island.  Lyon Park is located across the river from Demitz Park and is another access option.
    • Ben Hansen Park to Port Edwards Landing:  1.8 miles.  Nice prospect that includes paddling past some historic islands.  The Centralia dam should be an easy portage (east bank by golf course).
  • Port Edwards Landing to Nekoosa/Riverside Park:  3.6 miles.
    • Port Edwards Landing to Port Edwards Powerhouse:  1.3 miles.  A half mile portage is required.  A very scenic boulder field is located below the dam.  At high levels, the rocks are submerged and produce a half mile stretch of rapids (some strong).
    • Powerhouse to Moccasin Creek Landing:  1.8 miles.  A generic wooded stretch that isn't super interesting.
    • Moccasin Creek Landing to Riverside park:  0.5 miles.  During the draw down, this stretch had nice boulder fields and rapids.
  • Riverside Park to Hwy 73:  0.8 miles.  An ok stretch of the river.  There are scenic cliffs south of Hwy 73, but these are past the dam warning line.  Hwy 73 is not a good access option.
  • Hwy 73 to Point Basse Ave (Portage of the Nekoosa Dam):  1.5 miles.  A difficult 1.5 mile portage through downtown Nekoosa.  Don't try to portage the south bank.  There is a steep hill, cliffs, and large Domtar fences to deal with.
  • Point Basse Ave to Jim Freeman Memorial Boat Landing:  0.8 miles.  A generic stretch going by historic Point Basse.  If you're willing to backtrack to the dam, you can see scenic boulder fields (during low flows) and a few cliffs.  Point Basse Ave is a somewhat speculative access, but it seems public and doable for launching.
  • Jim Freeman Memorial Boat Landing to Plank Hill Small Boat Access:  2.0 miles.  Generic stretch.
  • Plank Hill Small Boat Access to 19th Drive Landing:  5.3 miles.  Features 2 epic sand banks. The main channel has some sand bars.  The main side slough to the west looks interesting.
  • 19th Drive to the Petenwell Dam:  14.9 miles.  This is Lake Petenwell which is a large and challenging lake for paddling.  Waves and strong winds are frequently an issue.  There are countless alternate access options on the lake itself.  See the overview map for more info.
  • Petwenwell Dam to Ganter Lane Landing:  3.8 miles.  This stretch isn't too impacted by dams and may have nice sandbars at low levels.
  • Ganter Lane Landing to Castle Rock Lake Dam:  10.7 miles.  Castle Rock Lake is likely too big (wind/waves) for enjoyable paddling.   There are many alternate launch options along the shore.
  • Castle Rock Lake to the Lemonweir River 10 miles.  An ok section.
  • Lemonweir River Mouth to the River Bay Landing:  7 miles.  The first half of the classic Upper Dells.
  • River Bay Landing to Blackhawk Island 6.5 miles.  Second half of the classic Upper Dells known for its fantastic outcrops.  Note, the Blackhawk Island landing is no longer accessible without special permission from the local 4H club.  
  • Black Hawk Island to Wisconsin Dells Dam:  2.0 miles.  More nice sandstone outcrops.  You can take out at a public ramp off Indiana Ave or portage the dam and take out SW of the dam by a launch off Wisconsin Dells Pkwy/Hwy 12.
  • Dells Dam to Indian Trails Landing:  6.2 miles.
    • Dells Dam to Newport Park:  2.2 miles.  This is the heart of the famous Lower Dells with many scenic outcrops.  Unfortunately jet boats are a serious plague on this stretch.
    • Newport Park to Indian Trails Landing:  4.0 miles.  Features the famous "Sugar Bowl" and four super cool caves.  The outcrops soon disappear and this stretch is mostly uneventful (but peaceful) big river paddling.
  • Indian Trails Landing to Pine Island Boat Ramp:  9.8 miles.  Few paddle this stretch as it isn't as interesting.  But...it does have a good concentration of sandbars and few competing paddlers for them. 
  • Pine Island Boat Ramp to Portage/Hwy 33 Access 6.0 miles.  Not an elite section that is lacking in cliffs and bluffs.  It does have good sandbars though.
  • Portage to Baraboo River/Thunderbird Road:  5.2 miles.  A good section with great sandbars, but can be crowded in the summer.
  • Baraboo River to Dekorra Park:  2.5 miles.  River splits into several channels which can be fun to explore.
  • Dekorra Park to James Whalen Memorial Park 6.6 miles.
    • Dekorra Park to Camp Rest Park:  5.1 miles.  A terrific section with rock outcrops, large island deltas, hidden sloughs, and nice sandbars.  Unfortunately this part of the river is popular with motorboats and jet skis which can be a plague.  Multiple alternate access options.
    • Camp Rest Park to James Whalen Memorial Park:  1.5 miles.  Not a great section because of the open water paddling, powerboats and big waves.  The west shore though does have nice outcrops.
  • James Whalen Memorial Park to Prairie du Sac Dam:  14.5 miles.  The river turns into “Lake Wisconsin” here...an inadvisable section due to the amount of open water paddling required.  There are many intermediate access options.
  • Prairie du Sac to Mazomanie:  8 miles.  An ok section of the Wisconsin but lacking in sandbars. 
  • Mazomanie to Arena 9.7 miles. A great section with nice sandbars and scenic bluffs. 
  • Arena to Hwy 14:   8.0 miles.  Good section with a high concentration of sandbars.  One of the more popular legs on the Lower Wisconsin.
  • Hwy 14 to Hwy 23/Spring Green:  2.2 miles.  Neat mini-section with sandstone outcrops.  Very popular in the summer.
  • Spring Green to Lone Rock:  7.4 miles.  Another fine sandbar/bluff section with some nice rock outcrops too.
  • Lone Rock to Gotham:  8 miles.  This stretch has super impressive rock outcrops and sand banks.
  • Gotham to Muscoda: 7 miles.  Cool limestone rock outcroppings.
  • Muscoda to Port Andrew:  7 miles.
  • Port Andrew to Boscobel:  9 miles.  Wooded islands start to get massive.
  • Boscobel to Woodman/Big Green River:  9 miles and start of the less paddled stretch of the Lower Wisconsin.  Far fewer sandbars from here to the mouth, but good bluffs and side sloughs to explore.
  • Woodman to Adiantum Woods State Natural Area:  3.9 miles.
  • Adiantum Woods State Natural Area to Millville:  3.8 miles.
  • Millville to Bridgeport:  5.3 miles.
  • Bridgeport to Wyalusing (the mouth):  9 miles.
