2020 LILSA AGM:
Due to COVID19, LILSA will likely not be able to hold in person information events and Flowering Rush digs in 2020. If this changes, we will let you know!
We are going ahead with our 2020 AGM which will be held virtually using Zoom. This will be held on Saturday, Aug 15 at 9:30 AM. We will have Petra Rowellfrom and Annlisa Jensen the North Sasketchewan Watershed Alliance presenting the Sturgeon River Watershed Management Plan. This will include information on what can be done to improve water quality in our lakes.

President's Message 2019:
LILSA is a not-for-profit volunteer Society committed to promoting the protection of Lake Isle and Lac Ste Anne. Our goal is to improve the quality of our lakes. We have two main concerns: the prohibitive noxious weed, Flowering Rush, and Blue Green Algae (cyanobacteria) in our lakes.
Flowering Rush is a prohibitive, noxious weed invading Lake Isle. The County of Lac Ste Anne, the Summer Villages of South View, West Cove and Silver Sands, the Alexis Nakota Sioux Nation and LILSA applied for and received a $298,500 ACP Provincial Grant to collaborate on identifying the best practices to eradicate Flowering Rush. The west end of Lake Isle is heavily infested and is spreading east towards the bridge on Range Road 52. Our intent is to map the shores of Lake Isle and dig out the smaller plots by hand. The grant host, the Summer Village of Silver Sands, has hired a Project Manager and two summer students to work on this project. In addition, the Alexis Nation has received a $30,000 grant to hire six labourers, supervised by the Project Manager,
to work on mapping and digging of Flowering Rush. Our workers will be canoeing, kayaking and walking along the shoreline of Lake Isle during July and August. Please welcome them.
The Sturgeon Watershed Alliance has completed over $300,000 worth of studies over the past 3 years on the Sturgeon River Watershed. The first draft of the study’s report has been vetted by elected officials and is currently at the second draft stage to be reviewed by the technical committee. The goal of this study is to have all Municipalities across the watershed adopt the policies and best practices for watershed stewardship. The target date for the release of this document is the fall of 2019.

LILSA's has two main focuses: Flowering rush and Blue-green algae.
Flowering Rush is a prohibitive noxious weed which displaces native vegetation such as rushes and cattails which are 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 black bird to perch on, leaving them to find other habitat elsewhere. Flowering Rush depletes shoreline biodiversity not only of plants but of insects, birds, and mammals. 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 (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 going into our lakes. Specifically, the nutrients Phosphorus and Nitrogen increase the amount of Blue-green algae in our lakes.
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.
LILSA would like to thank the following groups for providing financial support to our projects for 2014/2015:
