Meet the Monsters Haunting the Waters of the Fox Valley and Green Bay
Forget Michael Myers—the real monsters this Halloween are lurking beneath the surface of the Fox-Wolf Watershed! As you plan your spooky adventures, whether you’re trick-or-treating in the Fox Valley or Green Bay, meet the environmental threats that haunt our lakes and rivers. These villains won’t be defeated with a hockey mask or kitchen knife, but with a little teamwork, we can keep our waters monster-free and Halloween fun watershed-friendly. 🎃
Just as Jason Voorhees stalks Crystal Lake, these environmental villains silently threaten our waterways. From slimy algae to invasive zebra mussels, these monsters might be out of sight, but they’re dangerously real. Let’s meet them—and learn how to fight back!
The Phosphorist
“Possessing Waters, Spewing Green Goo!”
Where It Strikes: Fox River, Lake Winnebago, Green Bay
The Phosphorist is here—an evil force that takes control of lakes and rivers, just like a demonic possession in The Exorcist. It uses phosphorus from fertilizers, grass clippings, and animal waste as its unholy fuel, spreading thick, green algae blooms that choke the life out of every waterway it touches. Under the Phosphorist’s grip, fish gasp for oxygen, plants wilt, and the once-beautiful waters are transformed into slimy, stinking nightmares.
Like a possessed soul, the lake becomes corrupted—its clear waters replaced by murky, algae-filled sludge. And just like an exorcism gone wrong, the Phosphorist keeps returning after every storm, bringing new blooms and foul odors. Unless the right steps are taken, this toxic force will haunt our rivers and lakes forever.
How to Fight It:
- Use fertilizers only when necessary, and keep grass clippings away from storm drains.
- Support watershed-friendly practices with help from the Fox-Wolf Watershed Alliance.
Clingers
The horde just keeps coming!
Where It Strikes: Lake Winnebago, Fox River, Wolf River
Clingers are like Clickers from The Last of Us—unstoppable, relentless, and spreading wherever they can latch on. These zombie-like zebra mussels invade lakes and rivers, clinging to boats, docks, and water pipes with an iron grip. Once they infest a waterway, they multiply fast, draining the nutrients that fish and plants need to survive. With fewer native species thriving, the water becomes too clear—making the perfect environment for harmful algae to grow.
Just like in a post-apocalyptic world, Clingers creep silently from lake to lake, hitching rides on boats and fishing gear. Their jagged shells litter beaches, cutting into bare feet, while colonies clog water pipes and infrastructure. Without action, Clingers will spread through the Fox-Wolf Watershed, turning vibrant ecosystems into lifeless wastelands faster than a horde of Clickers on the move.
How to Fight It:
- Always inspect your boats and equipment after use, remove any plants or animals, and drain all water to stop the spread.
- Learn more about prevention from Wisconsin DNR: Clean Boats, Clean Waters.
Lampires
The Bloodsuckers of the Watershed
Where They Strike: Great Lakes, Rivers, and Streams near Green Bay
Beware the Lampire—a sea lamprey terror lurking in rivers and lakes, feeding on fish like a vampire of the deep. With its suction-cup mouth full of sharp teeth, it clamps onto its prey and drains their blood, leaving them too weak to survive. This invasive creature has slithered into the Great Lakes and waterways near Green Bay, turning once-thriving ecosystems into watery graveyards. Just like the infamous Nosferatu, it sneaks in silently, looking creepy and leaving destruction in its wake—making it harder for native fish to survive.
How to Fight It:
- Back programs like the Great Lakes Fishery Commission that work to manage the sea lamprey invasion.
- Follow fishing rules—some fish species help control the spread by feeding on lamprey larvae.
- Get involved in watershed conservation efforts to stop these aquatic vampires from expanding their reach.
Floody Krueger
A Nightmare on Every Street!
Where It Strikes: Parking Lots, Streets, and Sidewalks
Freddy haunts dreams with terror, Floody haunts streets and waterways with polluted runoff. As rain pours down, stormwater gathers oil, fertilizer, pet waste, and trash, sweeping it all into nearby rivers and lakes. Fish and plants suffer in his toxic nightmare, while algae thrive on the chaos. If this waterborne slasher isn’t stopped, his sludge-filled trail will make rivers too dangerous for swimming and fishing—turning every trip to the lake into a horror story.
How to Fight It:
- Plant rain gardens and install green spaces to absorb runoff before Floody can strike.
- Pick up pet waste and keep storm drains clear to cut off his polluted supply.
- Work with your local community on stormwater solutions—learn about the Northeast Wisconsin Stormwater Consortium.
Trashenstein
“It’s ALLLITTER!”
Where It Strikes: Beaches, Parks, and Shorelines
Like Frankenstein’s monster, Trashenstein is cobbled together from every discarded bottle, wrapper, and bag. With every piece of trash, it surges back to life—“It’s aliiive!”—growing larger and more destructive. Trashenstein clogs rivers, traps animals in plastic, and turns parks into horror scenes that even Victor Frankenstein would fear. The more litter left behind, the harder it is to stop this monster from rampaging across shorelines and waterways.
How to Fight It:
- Don’t litter—cut off Trashenstein’s lifeline.
- Join area clean-up efforts to dismantle the monster bit by bit.
