‘C’ grade for Raisin River
Creeks get ‘F’ on report card
A C average is the grade the Raisin River gets in the latest “report card” issued by the Raisin Region Conservation Authority.
The basin earns a C+ for forest conditions and surface water quality and a C for wetland conditions.
Those are the same scores that were handed out in 2007.
Some parts of the watershed score very poorly in the most recent evaluation. For instance, some South Glengarry water courses get F grades in all categories.
In the Finney Creek watershed, there is no wetland cover.
