French River Phosphorus Levels: 2009

2009 was the third year of renewed water sampling activity on the river and 69 samples were returned to the Dorset lab. Once again, there were increased phosphorus levels in the spring, with the highest levels in Wolseley Bay.

A new site was added at Bear Lake (Stn# 274-1) upstream of Wolseley Bay. This station showed some of the lowest phosphorus levels in the test area, in stark contrast to high levels seen in Wolseley Bay. Levels mid way down the North Channel at Daust Bay (Stn# 7262-1) were quite low this year, indicative of a slow rate of drainage from Wolseley Bay into the North Channel.

Elevated levels were also seen in the Delta area at stations 7262-10 and 11. The levels were a bit lower in 2008, possibly because the samples were taken earlier in the year in 2009.
