2013 - Overview of Pigeon Lake Water Quality, Sediment Quality, and Non-Fish Biota

“In 2013, Pigeon Lake was sampled 15 times from June through September (Table 2-1). Water quality sampling was conducted at profile and composite sites…Data collected from Pigeon Lake in 2013 (not including fisheries information) consisted of:

• Weekly lake water quality

• Weekly to bi-weekly stream water quality samples

• Groundwater quality samples

• Sediment quality samples

• Zooplankton and phytoplankton taxonomy (weekly), and cyanobacterial bloom quality samples

Overall, data collected provided insight into potential causes of blooms, helped support the development of 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. Detailed lake and watershed sampling contributed greatly to the existing data and knowledge base on Pigeon Lake.”
