Mississippi River – McCartney Lake



Date Paddled: July 12th, 2020
Put-in: Lynn Hollow Boat Launch
Take-out: Lynn Hollow Boat Launch
Distance: 14.5 miles (round trip)
Time: 5 hours 2 minutes (figure 2 mph)
Gradient: Slow current
Water Level: Mississippi River @ Clayton, IA 13.18'

One of the more obscure and overlooked paddling sections on the Mississippi is from Cassville to the mouth of the Grant River.  The river here can be divided in two.  The south half by Iowa is the main channel.  This is fairly open and features most of the heavy boat traffic.  The north side by Wisconsin is in contrast sheltered and contains a series of islands, lakes, sloughs, bluffs, and outcrops…which makes it the more scenic option for paddlers.

Paddling this entire stretch could be a bit overwhelming as it is over 18 miles long, but it can easily be subdivided by numerous intermediate landings.  We considered multiple options…such as paddling Far Nuff Landing to Lynn Hollow Landing…but ultimately decided to do a round trip with a small motor on the canoe.  Typically I prefer not to do trips with motors as they make noise, you’re constantly being buffeted with wind, and by going fast you miss a lot of subtle details in the river (changes in current, wildlife, plant life, etc…).  But in this case it was practical as we wanted to explore a lot of the river, we wanted to do a round trip, and we weren’t super interested in paddling the few open water sections of this trip.

We started the trip at Lynn Hollow Landing which is technically on of Spring Lake.  This is a nice access backdropped by a scenic cliff, American Lotus fields, and a large archipelago of islands.  While we didn’t explore these particular islands in depth, we were told by a canoer who launched ahead of us that there were good sandbars for camping hiding on some of them.  The few that we went past however were mostly muddy and full of poison ivy.

The first thing we did was to head downstream from Lynn Hollow to check out the “last” of the Cassville Cliffs.  After about the second outcrop the river opens up significantly into a vast lake and most of the cliffs go away (although there are additional ones way down by the Platte and Grant Rivers).  So we didn’t see the point of going all the way to Potosi and turned around to start our main trip upstream of Lynn Hollow where the best scenery was.

We soon exited Spring Lake via “Snyder Slough”.  While this trip mostly lacked current, the exception was at the entrance to Snyder Slough where the current was noticeable.  After that we mostly hugged the shoreline which was where the most scenic bluffs were.  Here the cliffs appeared often…perhaps once every 2000 feet.  Growing atop several of these were scenic red cedars.  This area is actually even more striking in the spring/fall when trees are bare and the cliffs are much more visible and dramatic. 

At the base of the bluffs was a busy two-way railway with trains passing us maybe once every 45 minutes.  This is one trip where you are guaranteed to see a train!  Note these Mississippi trains are fast and you don’t want to mess with them.  When crossing the tracks make sure to look both ways after a train passes as another train may be coming from the opposite direction in a hurry and you won’t hear it. 

We then came to McCartney Landing which is a good access option.  This landing is actually not on the Mississippi, but rather on McCartney Creek which itself is an attractive paddle and can be explored upstream for some ways.

After that we headed out on the river and took a lunch break on Bertom Island.  This is a very unique island created from dredge spoil taken from the main channel.  Inside of the island is a self-contained lake which is a nice habitat for wildlife.  Along the western side of the island was a thin sandbar which made for a nice picnic area.  The island is backdropped by one of the larger cliffs along the north shore which made it very scenic.

Upstream of Bertom Island we explored additional back channels and sloughs…some of which dead-ended.  One of the trip highlights were the huge patches of American Lotus.  These are quite different from the regular lilies you see on typical Wisconsin creeks.  American Lotus are much larger and have waxy surfaces which cause water on them to pool in unique concentric puddles.

We then took “Coalpit Slough” upstream to Far Nuff Landing, which is another nice access.  Far Nuff roughly marks the start of Bertom Lake, which contains a huge labyrinth of sloughs and islands.  We decided not to continue to Cassville which would have entailed a time-consuming route through this maze.  Instead we took in the last of the major cliffs (there aren’t many more closer to Cassville) and turned around.  In years past, we would have seen the Nelson Dewey coal plant by now.  This was an “iconic” part of Cassville and its smoke stack could be seen for miles.  Thankfully this plant was recently decommissioned and imploded.

In summary this was a neat trip with some of the larger cliffs you’ll see in Wisconsin.  Other highlights included the driftless bluffs, large patches of American lotus, and abundant wildlife.  These islands and sloughs downstream of Cassville harken back to yesteryear when more of the Mississippi was like this…a braided series of islands and channels.  But unfortunately much of the river is now dammed and channelized which has severely mutilated the river.  This trip won’t be for everyone, as there is a decent amount of open water paddling which some might find boring.

For paddlers that like to camp, this trip could be a unique experience.  You could launch at Cassville, camp on one of the islands (the best are near Lynn Hollow Landing), and then take out near the Grant River.  Most islands were a bit mucky and overgrown, and would likely require hammocks instead of tents.  But some islands do have nice sandbars when the river is low which I confirmed with Google Earth’s historical images. 

Side note…if you find some of these lake and slough names confusing you might want to check out this Army Corp of Engineers map.  

Noteworthy Wildlife:

This was a good trip for wildlife.  Sights included many dragonflies (some emerging), a few jumping fish, many caddisfly exuviae, and a fat woodchuck.  We also saw a lot of birds including eagles, turkey vultures soaring over the cliffs, swallows, a Carolina wren, and a great blue heron.  On Bertom Island there were many destroyed turtle eggs and empty clam shells….likely caused by raccoons.  The highlight was a large pelican flock we saw near the end of the trip.

Local Diversions:

Cassville Ferry:  Between Prairie du Chien and Dubuque there are no bridges over the Mississippi (a distance of 50+ miles).  But…halfway between these two cities is Cassville and its ferry which shuttles vehicles between Iowa and Wisconsin.  If you’re used to the Merrimac Ferry, this is quite different.  It’s a tug and mini-barge (no cables) that does an inverted jackknife move when it wants to dock and actually travels more upstream/downstream than across the channel (it’s about a one mile trip).  Note, the ferry does cost $15 per vehicle (cash only) and it doesn’t have a super consistent schedule.  There is a button you can press to signal the ferry when you want to be picked up.  Round trips cost double ($30 per vehicle).  The ferry will often shut down when the Mississippi is high (you can check availability from its facebook page).
 
Nelson Dewey State Park This is located just north of Cassville.  This isn’t a huge park or super popular…but it does have a nice camping area as well as an overlook with a vista of the Mississippi.
 
Stonefield Historic Site:  A huge re-creation of an early 1900s village located just below Nelson Dewey State park and run by the State Historical Society.  The land, along with Nelson Dewey State Park, were originally part of the 2000-acre estate of Nelson Dewey, the first governor of Wisconsin.  Click here for pictures.

Put-in (and Take-out):

Lynn Hollow Public Access:  This is a nice public access with free parking, outhouses, and isn’t too busy.  The only downside is the access road goes under a very low railroad bridge (7′ 3″) which might be an issue for some vehicles with boats on top.

Alternate Access Options:  There are a number of options on the Iowa side (the main channel) and the Wisconsin side (where the sloughs and cliffs are).  Generally speaking the most scenic bluffs will be between Far Nuff Road Landing and Lynn Hollow Landing along the Wisconsin side.  For more information and options see my McCartney Lake Overview map.

Shuttle & Rental Information:

Round Trips:  We attached a motor to our canoe which made a round-trip viable.  For paddlers, round trips are also viable but should be planned carefully.  The current isn’t too strong for the most part, but it does pick up steam when funneled between islands.  For round-trippers, it’s suggested you go upstream first and you plan a trip when water levels are on the lower side (the current slows significantly when water levels are down). 

Bike Shuttle:  This is a difficult river to bike shuttle because the roads are hilly and not very direct.  Lynn Hollow Road to Far Nuff Road would be 10.8 miles and 433′ of climbing.  Something like Lynn Hollow Road to McCartney Landing would be a more manageable 4.7 miles with 299′ of ascent…but that would be a short paddle.

Hazards and Concerns:

Wind:  This is a very exposed section of the river.  Check the forecast before committing to this trip.

Open Water Paddling:  Some parts of McCartney Lake are quite wide so beginners should stick close to shore in case something goes wrong.  Life jackets are also recommended.

Wake:  McCartney Lake and the adjacent sloughs are actually quite insulated from the main channel.  You won’t see barges, but will see a few fishing boats…most won’t create that much wake and this is actually a relatively calm part of the Mississippi.  But if things get windy this can change and large waves can develop.

Getting Lost:  Some of the islands and sloughs are not logically arranged…nor do they perfectly correspond to online maps.  Some sloughs also close up in low water, while new ones are created in high water.  It’s recommended you bring a GPS and have access to the latest satellite maps.

River Depth and Navigability:

Nearest Gauge:  Mississippi River @ Clayton, IA  (Trip done at 13.18′)

  • 0-12.5′:  These are low levels.  The current should be slow then which would be good for round-trippers, but not those who do one-way trips.  Some parts will be too shallow for motors, but paddlers should be fine.  This is also a good depth for campers.
  • 12.6′-13′:  An average depth and good target range. 
  • 13.1′-14′:  An above average depth.
  • 14.1′-16′:  A high depth with decent current.  This might be bad for round-trippers but good for one-way paddlers.
  • 16.1’+:  A very high depth with fast current.  I suspect this area of the Mississippi can be paddled in high water as it’s sheltered from the main channel but caution should be exercised.

Other McCartney Lake Area Trips:

Hwy VV/Old Power Plant to the Cassville Public Docks:  1.2 miles. This is an open water paddle on the Mississippi by the community of Cassville.  Highlights are seeing the ferry do its one mile shuttle or seeing barges (which aren’t visible from the downstream sloughs).

Cassville Public Docks to Far Nuff Road Landing:  5.4 miles.  After Cassville, take the north channel when the river forks.  Then look for a small  channel on your left which will lead to the Wisconsin side of the river.  This is the Bertom Lake area which has many small islands and sloughs that are protected from the main channel.  The “Bertom Lake West Access” may be impassible in low water…if that happens you’ll have to continue a few extra miles downstream and use the “Bertom Lake South Access” instead.

Far Nuff Road Landing to McCartney Landing:  3.0 miles.  A more open stretch but with some of the most scenic bluffs in the area.  Bertom Island is located on this route and has a nice sandbar on the west shore.

McCartney Landing to Lynn Hollow Landing:  2.1 miles.  A good leg with scenic bluffs and many side sloughs and islands to explore.  While most islands are a bit mucky, there are occasional sandbars that appear in low levels that would be great for camping.

Lynn Hollow Landing to Potosi Point:  4.4 miles.  The river really opens up downstream of Lynn Hollow.  There are some rock outcrops but not as many.  This is a less interesting section…highlights include paddling past the mouth of the Grant River and Potosi Point which is a scenic area.

Potosi Point to Grant River Recreation Area:  1.7 miles.  More open water paddling that isn’t as interesting…but there are scenic bluffs near the mouth of the Platte River.

Other Mississippi Trips:

The Mississippi is both a blessing and a curse for paddlers.  While rich in beauty and majesty, it can be problematic to paddle due to high wind, current, wake, powerboats and barges.  The Upper Mississippi is frequently dammed and subdivided into “pools” of which there are roughly 11 in Wisconsin.  Generally speaking just upstream of a dam, the river is the least interesting (few islands, deep, monotonous, few sloughs, and a wide channel).  But on the upstream side of pools there are often many sheltered islands and sloughs that offer unique paddling experiences. 

For a list of Mississippi water trails see my overview map or use the bullet list below.  Thanks to the US Fish and Wildlife Service for many of these suggestions.  Check them out for more details.

Chippewa River:  6.8 miles.  Chippewa River Landing to Tim’s Slough Landing.  Basically the last part of the Chippewa River that connects with a slough on the Mississippi.  Avoid in high water.

Nelson-Trevino Trail:  South of the Chippewa River, Hwy 25 cuts across the river through a slough and over a grade.  Many landings to pick from.  Most paddlers venture south and then back north to one of the landings.  The main water trail is roughly the biggest loop you can take south of Hwy 25 while remaining in the slough.  Avoid in high water and high wind.

Finger Lakes Trail:  6.1 miles.  North of the Zumbro River mouth, there is a sheltered collection of sloughs and lakes you can paddle.  The main water trail skirts the south edge.  In low water, some portages may be required.  For a launch/take-out, use Pioneer Landing in Minnesota.

Halfmoon Trail:  5.1 miles.  Mixture of paddling on open sloughs, narrow sloughs and on the main channel.  Use Halfmood landing for an access.   Difficult in high water and when vegetation is out in late summer.

Verchota Trail:  11.3 miles.  A long upstream paddle up the main slough then you double back mostly on the same trail.  Use Verchota Landing for an access.  Difficult because of its long length and upstream paddling.

Aghaming Trail:  6.7 miles.  Start at the park in the main channel and float downstream until you find a gap in the slough which you can paddle upstream to explore.  Turn back when done.  Access at Latsch Island Park and Landing.  Some upstream paddling in the main channel.  Not usable in high water.

Voyageurs Canoe Trail/Perrot State Park6.5 miles.  Your best bet is to do a one-way trip from Hwy 35 to S. Park Road.  Very scenic.  Completely sheltered from the main channel and technically the Trempealeau River. 

Long Lake Trail:  5 miles.  Just south of Trempealeau, you can launch at Long Lake Landing and explore the Long Lake Slough.  Head south, then you can double back by the marsh.  Just a little bit of open channel paddling.

Brown’s Marsh Canoe Area:  More of a lake paddle and a way to experience Brown’s Marsh.  Access at Lytles Road.

Lake Onalaska Trail:  Technically the last miles on the Black River.  Been on my to-do list for a while…  Lytles Road to Fred Funk Landing is 4 miles, while Lytles to Mosey Landing is 8 miles.

Goose Island Trail:  8 miles.  A nice paddle around Goose Island.  Mostly simple sloughs but there are nice bluffs.

Reno Bottoms Trail:  3-14 miles.  Put in on the Minnesota side and float down a long slough.  Many intermediate take-out options.  Access at Reno/Hwy 26 & New Albin.  Some of the launches can be underwater during high depths. 

Blue Heron Trail:  3-7 miles.  Trip cuts across the Upper Iowa River mouth.  Know little more.  Access points at New Albin and Blackhawk Park.

Ambro Slough:  8 miles. Very similar configuration to Wyalusing.  You can paddle up the slough then downstream on the main channel if you wish.  The upstream slough by Harper’s Ferry also looks interesting.  Access at North Ambro Road.  8.2 miles if you do a full loop on the main channel.

Wyalusing:  5 miles. One of the neater areas on the Mississippi.

Johnson Slough:  6.2 miles.  Just downstream of Wyalusing on the Iowa side is another nice slough to explore.  Most launch at the landing, cut north through the slough and float back on the main channel.  Some current to paddle against.

Cassville Bluffs/McCartney Lake: 4-17 miles.  There is a protected series of sloughs and islands on the Wisconsin side that features many scenic bluffs and outcrops.

Dubuque Water Trail:  9 miles.  Start south of the dam by A.Y. McDonald Park.  Float down the western shore by urban Dubuque, past the Mines of Spain to Massey Station Road.  Easy to subdivide or to do round trip loops.   For further information see the official webpage for the trail.
