Lake Isle & Lac Ste Anne Water Quality Management Society (LILSA)

LILSA is a non-profit society committed to promote the protection of Lake Isle and Lac Ste Anne.  Our goal is to improve the quality of the water.  Our society is run entirely by volunteers.  We have many different projects to improve our lakes. Please join us at our events to learn more!

President's Message 2020:

 

Covid-19 has presented everyone with challenges.  Therefore, our AGM this year will go virtual with ZOOM.  Please access LILSA website www.lsawaterquality.com for details to sign on.  Our AGM will be on Saturday, August 15 at 9:30 am.  The AGM Agenda includes the election of Directors, financials, flowering rush update and our keynote speaker will address the newly released Sturgeon River Watershed Management Plan. 

 

The Sturgeon River Watershed Management Plan is available on our website.  The Sturgeon River Watershed group has received an additional $200,000 to develop an action and communications plan.  We hope to involve both river and lake residents in the use of best practices to protect our watershed.  We hope to have this information ready for the presentation at the August 15 AGM.

 

Flowering Rush continues to be a concern on Lake Isle.  We are pleased to report our 3-female crew from last summer will continue to work for the second year on the eastern half of Lake Isle.  They will be mapping and digging smaller plots of flowering rush.  We have found a couple of plots in the Sturgeon River joining our two lakes.  MLA, Shane Getson, is leading a group to address the spraying of the newly available chemical, Amazypyr.  This systemic chemical will be used in the heavily infested western half of Lake Isle.  We hope to spray up to 16 kilometres this summer.  We are working collaboratively with Chief Tony Alexis to ensure First Nations’ cooperation.

LILSA's has two main focuses: Flowering rush and Blue-green algae.

 

FLOWERING RUSH:

 

Flowering Rush is a prohibitive noxious weed that displaces native vegetation such as rushes and cattails which are the primary habitat for wildlife and primarily waterfowl. This plant doesn't provide the necessities of shelter for our shoreline birds.  It also isn't strong enough for the red-winged blackbird to perch on, leaving them to find other suitable habitats elsewhere. Flowering Rush depletes shoreline biodiversity not only of plants but of beneficial insects, birds, and mammals that rely on this area.  It also interferes with boating and reduces property value.

Flowering Rush is present in Lake Isle and if this problem is not dealt with it will extend into Lac Ste Anne as well.  We have an infestation in Lake Isle which has significantly increased in size from 2015 to 2020.  It used to be only in the west end but now has been found throughout the lake.  We are working with Alberta Environment, Alberta Invasive Species, Alberta Agriculture, County of Parkland, County of Lac Ste Anne and several other agencies to mitigate its progress and eventually eradicate it.

BLUE-GREEN ALGAE:

 

Blue-green algae (cyanobacteria) is present, and at times abundant, in both Lake Isle and Lac Ste. Anne.  To decrease the amount of Blue-green algae, we need to decrease the amount of nutrients (Nitrogen & Phosphorus) going into our lakes.  Primary sources of these nutrients are from agriculture, stormwater, wastewater, fertilizers, pet waste and certain soaps.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

How Can You Help the Lake?:

 

There are many things that property owners around a lake can do to improve the quality of water.  These involve decreasing the amount of nutrients going into the lake by both introducing less nutrients into the lake and increasing the amount of natural vegetation on our land.  Natural vegetation absorbs Phosphorus and Nitrogen before they can get into the lake.  Thus, if we have more vegetation on our property, there will be less nutrients in the lake.
