Pigeon Lake Watershed Management Plan
Pigeon Lake
Surface Area: 96.7 km2
Volume: 603 000 000 m3
Max Depth: 9.1 m
Mean Depth: 6.2 m
Shoreline length: 46 km
Mean Residence Time: > 100 yrs
Pigeon Lake itself, including the water quality and aquatic biodiversity
Lake Key Findings
Reducing the amount of phosphorus pollution entering the water of Pigeon Lake must be a key goal for managing the lake. Based on scientific evidence, sources of phosphorus that can be targeted for management including:
Loading from watershed lands such as from runoff, septic fields, and land use practices; and
Loading from the lake bottom (within the lake).
Objectives
Improve knowledge about phosphorous and cyanobacteria dynamics affecting the lake to reduce phosphorous loading and the intensity of algae blooms. As well as to investigate the feasibility and safety of in-lake options to reduce bloom formation and/or mitigate the effects of blooms.
