Sunset Lakes Water Testing Data

The SLOA board of volunteers has put a lot of effort into maintaining the water quality in the lakes and ponds of  the Sunset Lakes community. Here, Sunset Lakes residents can easily access the history of water quality in the lakes and ponds.

 

 

Sunset Lakes Water Testing Results

The clarity of the water is good in all lakes except Twin Lake, which has a lot of floating particulate – a natural phenomenon. The South Pond is looking better than it has in the past 3 years. Both the North and South Ponds appear to have “tea” coloured water which is likely because the ponds were dug from a bog. The water colouring is a natural, permanent condition and it is a condition that is exhibited by many lakes in Northern Ontario. The water in those lakes is clean but dyed tea colour (reddish-brown) because of the water seeping/flowing through a bog.
