As of 2017 we have confirmation of two invasive species in Wollaston Lake - Zebra Mussels & Eurasian Milfoil.  Please report any sightings using the OWL form or by sending an email to wlhca.news@gmail.com.  Below are two fact sheets to assist in the identification of both. 

Zebra Mussels

Eurasian Milfoil 

In 2015, WLHCA received reports of Cormorants scouting on Wollaston Lake.  Please report any sightings using the OWL form or by sending an email to wlhca.news@gmail.com. 

Cormorants

Water Species

When we introduce non-native species of fish into our fragile eco-system, unhealthy balances occur which can be disruptive or fatal to existing species. Many lakes just south of us in the Kawartha Lakes region have suffered from major infestations of invading species such as zebra mussels which can destroy fish weed cover/algae thus eliminating or reducing certain fish species, clog water lines and prove dangerous for swimmers due to the sharpness of their shells.

One way we can all help is by ensuring that the boats that we launch into our lake - either our own or the boats of visitors from other water bodies - are vigorously scrubbed to remove any and all boat algae or grime that could contain invading species. More specifically, here are steps you can follow to effectively limit invading species from taking up residence in our lake.

Commencing in 2009, we participate annually in the Ontario Federation of Anglers program called the ‘Invading Species Watch’ program. We take samples each summer from five different lake locations and submit them for analysis and the results arrive in the winter. To date we have not shown indications of zebra mussel larvae or spiny water flea but the growing presence in nearby lakes is worrisome and requires vigilance to stop the spread from infected lake.

The Ontario Federation of Anglers and Hunters (OFAH) and the Ministry of Natural Resources (MNR) are excellent sources for information and you are encouraged to familiarize yourself with the very informative content. For more information click on the link below.

Invading Species Awareness Program

Invasive Species: A Threat to Ontario's Biodiversity

Should you spot an invasive species in our lake, please do three things:

1. Remove it and place it in a container for specimen identification

2. Call the hotline number and report the species type and location.The number is 1-800-563-7711.

3. Notify the President for WLHCA, Richard Clark at richard.clark@rogers.com

Land Species

There are a number of invasive species (plants) some of which pose a health hazard as they are noxious. Specifically, the giant hogweed has been reported in the Wollaston Lake area as well as two sightings in North Kawartha Township (north side of Hwy 28 near Eels Creek Park & on Northey's Bay Road) .
