Health assessment of Tee Lake

What is considered a healthy Lake?

 

A. According to the  biologists of the Québec Ministry of Sustainable Development, Environment, Parks and Fauna

The 4 parameters below indicate the relative age of the lake. Lac Tee is still considered a young lake ( see the yellow squares in the "Classement du niveau trophique"  diagram below. . For a more detailed interpretation of the the meaning of these parameters click here to see explanations from the Ministère de l'environnement du Québec if you can read French or click here for an English explanation ( Ontario Cottage Owners web site)

i) Total Phosphorus                                                                                                                  Tee Lake Status:      3.1 ug/l         (summer 2017)        5.6 ug/l        (summer 2018)

ii) Chlorophyll                                                                                                                        Tee Lake Status:      2. ug/l           (summer 2017)        1.7 ug/l        (summer 2018)

iii) Dissolved organic carbon                                                                                                   Tee Lake Status:       5.4 mg/l       (summer 2017)        4.9 mg/l       (summer 2018)

iv) Transparency of the water in the lake                                                                                  Tee  Lake Status:       4.0 m          (summer 2018)         4.0 m          (summer 2018)

 B. According to a study conducted by the UQUAT of the surface and underground water of Tee Lake:

The mineral content of the surface water ( lake water)  meets the Health Canada standards for drinking water.

Please note that that this does not mean that the lake water can be consummed as is. 

The level of total coliforms exceeds the Health Canada standards and the water of Tee Lake must be treated before it can be consummed.

C. According to local residents and recreational boaters


A healthy lake is a lake whose water is clear, odorless and contains no bacteria, toxins or other agents that affect health when swimming.

More precisely;

 i. The amount of fecal coliform beings is less than 200 colonies (CFU) per 100 ml of water.  

ii. No blue-green algae were observed in areas where bathing is practiced 


 Condition of the water in the populated area of the lake (west bay) in August 2011: 2 UFC/100ml

Tee Lake Status: : no blue-green algae observed in 2018


D. According to fisherman

A healthy lake has a good amount and variety of fish that are not contaminated with dangerous chemicals and reproduce at a rapid pace.

Status of the lake:
 
A study was conducted in the summer of 2012. Click here to see the list of fish that were found.

 

Conclusion:

Today, the lake is in good health , but we must take good care of it . We must use common sense. We must not dump pollutants such as gas, oil, soap, or raw sewage water in the lake. While it will absord some, there is a limit.

The results presented below are valid up to the specific location on the lake or the sample was taken.
It is possible and probable that the values ​​vary depending on the location on the lake.
