    Working Together
    The Pigeon Lake Watershed Management Plan is all about working together for a common cause: a clean and healthy Pigeon Lake. Together we can make a difference!
  • Clean Runoff
    Clean Runoff
    Runoff from the land contains nutrients which enters the lake and increases the blue green algae. Collectively we can improve runoff water quality with a variety of actions.
  • Fertilizers and Soil Management
    Fertilizers and Soil Management
    Nutrients make the lake productive, which includes the promotion of algae including cyanobacteria, also referred to as Blue-Green Algae. 1 lb of phosphorus = at least 500 lbs of algae.
  • Riparian Restoration and Protection
    Riparian Restoration and Protection
    Transitional zones around the Lake and alongside tributaries are the last chance to filter nutrients before they run into the lake. A healthy shoreline protects the lake and is required for 80% of all the living organisms in the watershed!

    For Future Generations

The health of Pigeon Lake is at risk in large part because of how we have lived, worked and played around the lake.


Since 2012, Pigeon Lake, Alberta has been working toward a Watershed Management Plan . Until 2016, the Plan was being built in small pieces or Topics, which together add up to a whole plan. During 2016 -18 and entire Pigeon Lake Watershed Management Plan – 2018 was produced. Check out the Watershed Plan tab to get the latest.

The Pigeon Lake Watershed Management Plan is a joint initiative of the:

 The Pigeon Lake Watershed Management Plan (PLWMP) Goal: 

To improve the watershed’s natural environment and water quality by recommending action-oriented watershed policies and best practices that support the long-term health, protection and restoration of the watershed.

Endorsed by the watershed community, this collaborative initiative is producing a series of action recommendations, created with the input of local leaders and watershed experts and the Alberta Government.  Taking action is a responsibility of each Pigeon Lake resident, business and municipality. Together we can make a difference!  (see About).

This process marries the science and social considerations as practices and regulations are identified that people will support.  PLWA members, subscribers and PLWMP subscribers receive updates, notices and  on-line surveys to voice opinions and help shape the plan.  See “How to get Involved” below.

Key Reports & Events

Science Updates . . .  Extensive water studies in 2011-13 have been undertaken to guide the work of improving the water quality.

1.  A 2013 Overview of Pigeon Lake Water Quality, Sediment Quality & Non-fish Biota Report  Released August 2014.  Authored by the Alberta Lake Management Society (ALMS) it summarizes all of studies done and the findings.  

2.  The Pigeon Lake Phosphorus Budget.  July 2014  The Full Report and an Executive Summary are now available. Keeping in mind that the nitrogen correlation to chlorophyll-a (including algae) is very similar to that of phosphorus, it shows the sources of nutrients going into the lake and in the lake.
