Description

Fall index netting (FIN) is conducted each year during late summer and fall on selected Alberta lakes to monitor walleye and Northern pike populations. The abundance of adult fish as determined by the netting is used to help determine the risk to the sustainability of the fish population in a lake. This report presents the results of netting conducted in 2022 on Pigeon Lake.

Riparian assessment validation for North Saskatchewan Region Lakes

Description

This report documents the assessment of the performance of the GIS-based method used to evaluate the intactness of riparian habitats along the shorelines of Pigeon, Gull, Sylvan, and Buffalo lakes... More ≫

Description

This report documents the assessment of the performance of the GIS-based method used to evaluate the intactness of riparian habitats along the shorelines of Pigeon, Gull, Sylvan, and Buffalo lakes and their associated tributaries. Both desktop and field validation methods were used and the ability of the GIS assessment approach to capture relative differences in intactness locally and regionally was tested. Overall the method proved to be reliable for assessing and comparing the intactness of riparian management areas across large geographical areas.

Description

Pigeon and Wabamun Lakes are among the most heavily used recreational lakes in Alberta. Recently, apparent increases in algal blooms and fish kills have threatened the ecological integrity of these systems and may negatively affect their value to users. Limnological studies for the lakes are limited to the past 35 years, leading to uncertainty about the degree to which water quality has changed due to human activities. This study was initiated to fill this information gap from historical limnological data preserved in lake sediments. To better understand how to effectively manage cumulative impacts on the lakes, it is necessary to understand conditions in the lakes prior to development. Knowing these pre-development conditions will assist in setting reasonable and achievable goals for lake management.

Description

Severe cyanobacterial blooms in Pigeon Lake led to an increased concern about the lake's water quality. In order to better understand the ecology and chemistry of the lake and all the factors that may affect its water quality, an enhanced lake and watershed monitoring program was initiated in 2012 and expanded in 2013. Data was collected to provide insight into potential causes of blooms, to develop a nutrient budget in order to partition phosphorus sources in the watershed and to objectively evaluate what management approaches may be most appropriate for improving the water quality in the lake. This report provides a synopsis of all 2013 data collected.

Pigeon Lake phosphorus budget

Description

Occurrences of significant blue-green algae blooms have resulted in stakeholders at Pigeon Lake seeking management options to assist with reducing the frequency and intensity of such events. To more effectively target activities, a nutrient budget was developed to identify phosphorus entering the lake from external and internal sources. The results of the study showed a relatively even split of external and internal phosphorous sources. This indicates that while watershed management efforts must be pursued, there may be merit in exploring in-lake options for controlling phosphorus release to achieve a more timely reduction of nuisance blooms in the future.

Description

Due to natural soil characteristics and proximity to major urban centres, the Pigeon Lake watershed has undergone significant urban and rural development in the past decades. In recent years, occurrences of significant blue-green algae (cyanobacteria) blooms have been documented at Pigeon Lake. The following report includes an overview of cyanobacterial ecology and provides a list of in-lake and watershed management options for control of nuisance blue-green blooms and outlines the benefits, disadvantages and applicability to Pigeon Lake. While several options are available for stakeholders to pursue, it is important that a cost-benefit analysis be conducted beforehand and that stakeholders ensure that all applicable permits and approvals be obtained.

Description

The Pigeon Lake Fisheries Management Advisory Committee completed a five-year review of the Pigeon Lake Fisheries Management Plan in early 2009 and proposed some changes to the existing management plan. A survey was developed to obtain public feedback on the proposed changes, and was made available online and at two public meetings were held in Nisku and Wetaskiwin in March 2009. This report summarizes the results of the survey responses.
