Delton's Dubious Dye Dump


Allow Rat to begin by posing a basic home repair question.  Imagine for a minute that you live in a house with a leaky roof.  To be clear, we’re not talking about a rundown old rat hole (which has an undeniable charm of its own), but a genuinely nice place.  Every time it rains, water drips onto the wood floor.  After a few leaky years, the wood floor is in bad shape, completely water-stained, warped, and rotten.  Repairs are badly needed.  Do you pony up the dough for a nice new wood floor, knowing full well that the roof leaks?  

The Village of Lake Delton, known far and wide for its most river-rat-unfriendly of water skiing shows, is deeply invested in the appearance of its namesake lake, which drives its tourism-based economy.  Recently, the lake has been fouled with green water and algae blooms, caused by upstream polluted runoff that brings excess nutrients into the lake. 

The Village was apparently looking for a short-term fix to the dirty water that would allow water ski shows and other water-based recreation to continue unimpeded by unsightly and stinky algae.  So, they poured $30,000 worth (or some 500 GALLONS) of “AquaBlue” dye into the waters of Lake Delton.

Visibility in Delton's dyed waters is no more than a few feet.

AquaBlue, in case you are wondering, is a “non-toxic” dye for use in ponds—think of artificial blue ponds on golf courses.  Its contents are a trade secret—“concentrated acid blue dye #9” is all they tell us.  The dye, working its dark magic in Lake Delton at this very moment, prevents sunlight from penetrating more than a couple feet in the water.  According to its label, it provides a “beautiful blue tint” to the water.  Eyewitnesses confirm that it Lake Delton is indeed dark blue presently, with visibility at no more than a foot or two.

Rat’s pretty skeptical about this whole operation, which stinks as badly as the algae it was supposed to suppress.  Amid all of the murkiness over the dye, some light needs to be shed on a few important issues, such as the impact of this supposedly harmless dye.  If light doesn’t penetrate the dyed water beyond a couple of feet, how do sight-feeding fish find prey?  And if light can’t reach submerged aquatic plants, and the life-giving process of photosynthesis shuts down, what happens to the aquatic critters?

The question of whether or not the Village could legally dump the dye into public waters without a DNR permit is presently being evaluated by authorities, so stay tuned on that.  But it’s pretty clear that the dye was used as a workaround to the Village actually obtaining a DNR permit for any of the alternative treatments they could have sought.  You see, the dye isn’t registered (read: approved) by the EPA, which is likely why it was used.

And then there’s the not-so-insignificant issue of where the dye was dumped.  Deltonites ought to remember that their namesake “lake” is in truth Dell Creek, held up behind a dam.  (The creek infamously reminded us of this during the flood of 2008, when it blew out the dam and artificial lake, taking several homes with it).  Whether AquaBlue, PlayfulPink or RosyRed, the lake’s dye-tainted waters are currently draining out of the lake, and right into the Wisconsin River.  A greenish plume into the river was visible shortly after the dye was dumped.

Trouble is, the dye is meant to be used “in confined systems,” explicitly NOT for use in streams, rivers, or other flowing water bodies that are “not under control of the user.”  Rat can’t say with authority what kind of impacts the blue colorant will ultimately have on plants and animals downstream, but, he can say with full certainty that the Village of Lake Delton does NOT “control” the public waters of our state.

Rat knows desperation when he smells it.  And in his heart of hearts he can’t help but feel sympathy for folks yearning for crystal blue clean water.  The green plague seems to grow worse every year, wreaking havoc on Wisconsin’s rivers and streams.  Visitors flee from the hideous stuff and small businesses suffer the loss of income when summertime waters are marred by algae.  Here’s an idea: how about the fat cats on the hill in Madison pay as much attention to the concerns of small business owners affected by dirty water as they do the cries of other businesses who want regulations gutted?  They seem to only hear one type of small business owner…the one who hates government regulations.

Abstract art? Nope, just a boat landing dyed a pleasing blue tint.

In the meantime, any rat worth his whiskers could tell you that this expensive, temporary, and downright foolish “fix” (and significant expenditure of local taxpayer money) won’t clean up Lake Delton in the long term.  The only way out of this slimy mess is to look upstream and address polluted runoff problems, stopping the slime-causing sludge at the source. 

Remember our home repair question above?  The algae blooms in this case are merely a symptom of the upstream problem of polluted runoff, much like the rotten floor is a symptom of a leaky roof.  Treating the symptom does nothing to alleviate the bigger problem.  Fortunately, Wisconsin has tools in place, such as a progressive set of phosphorus rules, which allow us to holistically treat upstream “problems.”  But until we actually start looking for upstream solutions instead of downstream band-aids, quick “fixes” like Lake Delton dye dumps, Lake Menomin “scumsuckers,” or Lake Monona “solar bees,” are looking like damned expensive lipstick on the proverbial pig.

  1. Even if the pond is completely within your property; unless it probably is a swimming floor with non-percolating floors, as far as I know, it's still public water by mandate of law!

    1. But in order to access it you must cross private property, which is not a public right-of-way.

  2. This a part of your blog and I would like to clarify that this is not what happened.
    " (The creek infamously reminded us of this during the flood of 2008, when it blew out the dam and artificial lake, taking several homes with it)."

    The dam was not blown out at all during the breech in 2008. Flooding that year caused the lake to overflow and break through a portion of the earthen barrier between it and the Wisconsin River. Several homes slid into the lake. Lake Delton completely emptied, leaving a muddy lake bed. I was there, witnessed two of the homes fall into the rushing water. The dam was never compromised.

    1. Rat appreciates your comment, and acknowledges the error. The larger point, however, remains accurate, and that is that Lake Delton, like many of our "lakes" in Wisconsin, is actually a dammed river (or "impoundment"). We are often painfully reminded of this in flood events, as are we often during summer, when impoundments turn green from nutrients that come from miles upstream and flow down a river until a dam stops them.

  3. It’s amazing how many UNTRUE statements are put out on the internet.
    The cost of dyeing the lake, was NOT covered by taxpayer dollars.
    .
    I am a lakefront property owner on Lake Delton. The village of Lake Delton is all about TOURISM. The majority of businesses in Lake Delton would no longer be in business if the tourists stopped coming. The taxes that I pay on my lakefront property are at least 3 times of what the average non lakefront property owners pay. I am also charged substantial fees for numerous permits that are required to provide rental lodging for tourists. I put forth a huge amount of effort to maintain a clean property and outstanding waterfront beach. Which would YOU rather spend a vacation on? A drab green looking lake, or a shinning bright blue lake. I applaud the village board for supporting all the tourism based small businesses and being proactive by taking action to beautify the lake.
    And regarding where the money came from, “Tommy Barlett President and long time Wisconsin Dells entrepreneur Tom Diehl says the cost was NOT covered by taxpayer dollars. The money, Diehl says, was taken from a pot of tourism-driven funds”.
    WELL DONE and thank you!

    1. Lakefront Property Owner, Rat's not going to debate you about the source of the funds, but "a pot of tourism-driven funds" sounds an awful lot like public money...

      That's much less of an issue of concern as is the actual dyeing of the lake. The question here is the issue of a short- term "fix" versus a long-term solution. Is dyeing the lake in the short-term good for the waterfront businesses and property owners whose bottom line depends on its appearance? Perhaps. Tourists vacationing in Lake Delton over the next couple weeks may enjoy the "pleasing blue" water, and return for future visits. Did this tourism bring an economic boost in the short term? Probably.

      Is dyeing the lake actually treating the upstream cause of the polluted water? Absolutely not. Is reapplication of $30,000 worth of dye going to fix pollution in Lake Delton? Not a chance. It is not a long-term solution, and this is the more important and larger issue that Rat has with the dye job.
