LILSA WINS 2020

McIntosh Bulrush Award!

 

Accepting the award on behalf of the group is member

Bernie Poulin, Mayor of the SV of Silver Sands​

Every year the Association of Summer Villages of Alberta, at our annual Fall Conference, presents the McIntosh Bulrush Award to an Individual or Organization that exemplifies lake stewardship activities. Use of personal time to improve: The environment of any Alberta Lake. Any lake shore.



The LILSA is a non-profit society run entirely by volunteers.  Their mission is to improve the quality of the water by educating residents Lac Ste Anne and Lake Isle on best practices and to encourage all municipalities within the watershed to adopt goals to achieve this mission.  They have an 8 member board made up of 6 elected and one appointed by the Lac Ste Anne County and one by the Alexis Nakota Sioux Nation.

For several years there has been increasing concern among the lake users that the water quality of Lac Ste Anne and Lake Isle may be deteriorating.  Complaints were made about increased blooms of Blue-green algae, weed grwoth and murky waters.  The shoreline of Lake Isle is also being taken over by Flowering Rush which is a prohibited invasive weed.

During July/August 2019, in collaboration with the Alexis Nakota Sious Nation, a very aggressive flowering rush digging program was completed on Lake Isle.  Lake Isle and the west end of Lac Ste Anne was also surveyed.  In 2020 their accomplishments included the removal of 51 truck loads of floating islands of Flowering Rush from the west end of Lake Isle.  Mapping of the west basin of Lac Ste Anne and extreme east end was completed. Other 2020 planned projects were postponed due to the pandemic.

Lake Isle and Lac Ste Anne State of the Watershed Report!

LILSA is very pleased to announce that our STATE OF THE WATERSHED REPORT for both Lac Ste Anne and Lake Isle is complete.  Please click here to review the report.

Sturgeon River Watershed Report!

The Sturgeon River Watershed Management Plan was finished in 2020!  This is a very important document as it includes our important information for Lac Ste Anne and Lake Isle.  Please click here to review the report.

President's Message 2020:

 

Covid-19 has presented everyone with challenges.  Our AGM this year went virtual with ZOOM.  It was on Saturday, August 15 at 9:30 am.  The AGM Agenda included 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.

 

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 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 opportunity for Blue-green algae to develop into a bloom, 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.  Such as, decreasing the amount of nutrients flowing into the lake while protecting and enhancing the amount of natural vegetation along the shoreline and landscape.  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.
