Lakes Appreciation Month offers an excellent opportunity to take the time to enjoy our local freshwaters and bring attention to the need for their protection. Celebrate their value by launching an action to protect, enhance, or rejuvenate a local waterway. The North American Lake Management Society (NALMS) offers various activities and resources including a Family BINGO Challenge, a Student Poster Contest, and a Social Media Challenge. Thank you for celebrating lakes with us!

Celebrating Dark Skies with a Star Party!

"Winter River Under The Milky Way" by Kate Reichl took second place in the 2024 Wisconsin Lakes and Rivers Photo Contest in the Natural Features In and Around Lakes and Rivers category. This dark sky photo was taken on Aurora Creek in Vilas County.
Changing Outdoor Lighting to Change Your World

"As shoreland property owners, we have a great opportunity to improve the world simply by rethinking our outdoor lighting," said a recent caller concerned with light pollution around their lake. It's true; reducing light pollution helps protect wildlife and ecosystems, benefiting migratory birds, pollinators, and other nocturnal creatures, which can be harmed by excessive artificial light. Since light pollution is reversible, you can make a tangible positive difference!

Folks in Oneida County are doing just that with events throughout the summer focused on connecting with our night sky and preserving dark skies in the Northwoods. Check out their upcoming Northwoods LIGHTS OUT! Event August 22-24 and learning opportunities at the Rhinelander District Library on July 31. There's even going to be a "Star Party" (scroll down to see details in the "Upcoming Events" section)!

We can all help ourselves and our neighbors by using more efficient lighting. Since inefficient fixtures waste money and use more electricity, this investment can quickly pay for itself. You can help preserve the beauty of the natural night sky, allowing your family and future generations to experience constellations and the Milky Way, which are otherwise obscured by sky glow. Properly designed sensible lighting can enhance actual safety and security more effectively than glaring, poorly aimed lights. This also helps maintain the desired quiet, open, dark space that shorelands offer at night for privacy and enjoyment.

  • Take a look at this interactive map of light pollution around the globe.
  • It's helpful to know the moon phases when making plans to search for constellations.

Phenology Fun Fact
Monarch butterflies are munching on milkweed!
If you find a milkweed plant, look for monarch caterpillars and butterflies. The monarch butterfly lays its eggs on milkweed leaves, because the growing larvae (caterpillars) eat only these specific leaves. Milkweed leaves contain a toxin that doesn't hurt the caterpillar, but it does make the caterpillar poisonous and bad-tasting to many predators. Because it eats milkweed leaves as a caterpillar, the monarch butterfly is also poisonous. 

Did you know...
  • Sap from milkweed was used by pioneers as a cure for warts.
  • The fluffy parachute of the seed is used by Native Americans to insulate moccasins.
  • The dried empty seed pods were used as Christmas tree decorations by early pioneers.
  • Wisconsin students collected 283,000 bags of milkweed fluff for use in military life jackets during World War II.
  • Milkweed is used as an indicator of ground-level ozone air pollution.

Lakes and Rivers Convention

SAVE THE DATE for 2026!
“Decades of Dedication”
April 15-17, 2026
When tackling a monumental challenge, it sometimes takes a long time to see results. The 2026 Wisconsin Lakes and Rivers Convention will look back on the long-term programs and the accumulated actions of countless people that have persevered through many decades. Their dedication has ensured that the programs developed in the '70s, '80s, and '90s are still going strong today. We will also celebrate the people who will continue to carry the torch for water protection and restoration into the future.
Rooms at the Holiday Inn Convention Center fill quickly. Make your hotel reservation now!

Photo Contest Celebrating 10 Years of Healthy Lakes & Rivers

Healthy Lakes & Rivers Celebrates 10 Years - PHOTO CONTEST
What better way to celebrate 10 years of the Healthy Lakes & Rivers program than with a Photo Contest?!
We want you to show us what you are doing to keep our lakes and rivers healthy!

Picture your favorite lake or river. 
What time of day is it? 
Are you along the shore? ...on a boat? ...in the water? 
Can you hear frog calls or the buzz of a dragonfly's wings as it snatches a mosquito above you?
What do you see, feel, and smell? 

In his book, For Love of Lakes, Darby Nelson wrote, "The vegetated zone of the lake is more than a place to delight the senses. It is a sacred garden. Loss of the garden plucks the pulsing green heart from the lake." 

If you live near a lake or river, you probably already know that every change you make to Mother Nature's design will affect the waterway and the other animals that live there. Striking a balance between enjoying our waterways and loving them to death is serious business, and we'd love for you to show us how you're part of the solution!

Send us your photos showing (photo contest categories):
1) Healthy Transformations: Before/After (ex: disturbed shoreline/restored shoreline with native flowers, shrubs, and trees; eroded shoreline/fortified with long-rooted native plants; erosion from runoff or runoff headed straight for the water/diverted and captured before getting to the lake or river)
2) Wildlife Enjoying Habitat (ex: heron in a native planting, frogs in a rain garden, fish swimming among the branches of a submerged tree)
3) People Making Healthy Lakes & Rivers Together (ex: planting a rain garden, fishing near fish sticks, enjoying your natural shoreline)

Winners in each category (plus the most clever caption) will enjoy prizes including Healthy Lakes & Rivers swag, a free workshop at the Wisconsin Lakes and Rivers Convention, inclusion of photo(s) in a future Wisconsin Lakes and Rivers Partnership publication, and bragging rights!

DEADLINE: SEPTEMBER 30, 2025

Say YES to Lakes
Check out the latest edition of the Wisconsin Natural Resources Magazine on ways you can “Say yes to lakes” through the Aquatic Invasive Species Fund. This science-based effort supports the DNR’s work to improve aquatic invasive species prevention and management. Your donation to the Aquatic Invasive Species Fund helps the DNR control and contain existing invasive species and stay ahead of potential new threats that might emerge. You can contribute as little as $2 via the DNR’s Go Wild portal or while registering or renewing your boat registration online, with an agent or by mail.
