annual Landing Blitz campaign runs June 26th – July 6th, 2024. Clean Boats, Clean Waters (CBCW) boat inspectors and educators will meet boaters at lake and river launches to remind them that by taking simple prevention steps, we all play a vital role stopping the spread of aquatic invasive species (AIS) like zebra mussels.
unable to care for their pet may think that releasing the animal is the right thing to do, however, releasing a pet is harmful for the animal and the environment.
strategy. Simply put, an ounce of prevention is worth a pound of cure. But if only it were just that simple. The variables and situations that can impact a waterbody may seem so limitless that it can be daunting to know where to start. As a lake resident, you might consider questions such as:
transporting and spreading AIS without proper decontamination. While everyone is required to “inspect, remove, and drain” per Wisconsin State Statutes NR40, these steps might not always be 100% effective especially for high-risk users such as service providers who are often working on multiple lakes in a single day and interacting with lake water and sediment in ways that recreational users are not. These kinds of service providers need to follow the same prevention steps that we all do, but they are not required to take the extended steps, such as spraying equipment with a bleach solution, making it all the more important for consumers to advocate for their lake.
provide responsible alternatives and a judgement-free environment for pet owners who can no longer care for their exotic animals.
collaborative effort ensures that these animals are given proper care and attention.
With 29 events planned for the year there are ample opportunities for pet owners to seek assistance in rehoming their animals.
while still leaving options open for herbicide treatment, if needed. Other management options include manual and mechanical removal as well as simply monitoring, since non-native plants can often co-exist with other native plants in a lake without taking over and becoming a nuisance.

Goldfish were first spotted in Hamilton Harbour in the 1960s, but largely died off in the 1970s because of industrial contamination. In the early 2000s, their population appeared to recover. Goldfish can tolerate a wide range of water temperatures, reach sexual maturation quickly, and can eat nearly anything, including algae, aquatic plants, eggs and invertebrates, Ms. Boston said.
