We are continuing to creating content for this page. Please excuse a couple typos, and I often do not used strictly proper taxonomic names, eg. giving genus name to actually mean the species in cases where only one species is present etc.
This page examines the South Saskatchewan River at Lemsford Ferry Saskatchewan, and continues west the lenght of the Oldman River to near Crowsnest pass in the Rocky Mountains, north on the Bow River to near Brooks, Alberta, and briefly, to the Red Deer River near Hanna. Lemsford Ferry signature species are distribued west to Taber, and Mountain signature species have an influence east to Ft. Macloed, and to some extent, to Taber. The Bow river is very polluted near Brooks (Scandia) and there is visible evidence that this pollution from the Bow River strongly impacts the South Saskatchewan River at Bow Island, and possibly Bow River pollution is impacting the South Saskatchewan River at Lemsford Ferry, with increased macrophyte and algal growth, and apparently rediuced biodiversity.
In my lab we have studied both the taxonomy and distribution of the species of aquatic insect in the Saskatchewan River. A tabulation is given in the first pdf below, and keys and illustrations are available for Saskatchewan species.
Nothing similar exists for Alberta as far as I know- no keys, etc. Thus, the pdf's below for Alberta wiII list families, genera, number of species (e.g. 3 Ameletus) etc. in a very informal way. It cannot be helped at this point in the absence of taxonomic studies for Alberta.
The pdf below gives species lists and distibutions from my lab on Saskatchewan species in the Saskatchewan River system:
Below is the record of a sampling trip to Lemsford Ferry. Some rare and interesting species are present (July 2010 fdf below), but what happened to all the biodiversity in 2010, compared to 2006 above? Could it be related to the pollution from the Bow River (below)?
