Most people who were at the lake between September 15th and 26th, may have heard about or actually noticed the formation of blue green algae blooms at the lake. We heard random reports that people saw what they thought was "gold-coloured pollen" floating on the water during this time period. These were very likely blooms.
On September 15th a few residents along the Lake Louisa North road reported significant pea soup coloured blooms in the water near the shore. The blooms continued throughout that very warm weekend there, as well as in Echo Bay and around Hope’s Island. They seemed to peak on Monday, September 18th when Claire Ropeleski took these photos on the north side of the lake where in some areas the pea soup colour reached as far as 20 feet out from the shore.
We asked the biologist, Vanessa Nadeau, who ran the shoreline mapping project for the LLPOA this summer, is there any way to minimize the chances of seaplanes bringing invasive species into the lake? She suggested the link to the video below.
The video is quite informative not only for pilots, but also for boat owners, as it illustrates clearly the damage some of these species can create, and how easily the transference can happen between bodies of water on a boat or a plane. As you know, Eurasian Milfoil is the one we are most concerned about and it is prominently featured in this video.
The results are available in French only.
Your stalwart group of volunteers have done yeoman service yet again - Roger Elliott and Bonnie Seale at Site A, John Perkins at Site B, Debbie and Randy Sinclair at Site C and Dany Miron and Jack Davis at all three sites as chemical testing was being completed. Here are the results of their efforts. Please note that, once again this year, we have exceeded the RSVL requirement for minimum number of tests. Note also that, unless we get a different direction from RSVL, we have completed our chemical testing series and will not be expecting to do that again for at least three years. The transparency testing continues every year.
Perhaps we can use the break to begin/complete other projects that have been left pending. Namely, shoreline mapping and periphyton observation. Additional volunteer support would be welcome to complete these daunting tasks.

This presentation focuses on the threats which the aquatic plant named Eurasian Milfoil present to Lake Louisa.
Eurasian Milfoil is an invasive species which will come to Lake Louisa if we do not take preventative measures.
The LLPOA hopes that all Lake Louisa residents from both Wentworth & Wentworth North watch this video.

The LLPOA serves all residents of Lake Louisa in both Municipalities of Wentworth and Wentworth-North. Our main goal is to help distribute important environmental information to all Lake Louisa residents and to promote sustainable environmental practices which will benefit our Lake.
The work of the LLPOA is supported by many dedicated volunteers from all around Lake Louisa. Please join the LLPOA and support our efforts to help keep Lake Louisa’s water healthy for future generations.
