Our lakes continue to have clear water
Each year, GORA volunteers conduct transparency tests on the lakes using Secchi disks and the readings are submitted to the Government of Québec (Développement durable, Environnement et Lutte contre les changements climatiques). The aggregated longitudinal data are used to reveal general trends in water quality.
GORA completed the lake water clarity testing for 2018.
Farm Lake = CLEAR lake - average of 5.3 metres over 8 samples
Hughes Lake = CLEAR lake - average of 4.6 metres over 8 samples
Little Hughes = VERY CLEAR lake - 7. 2 metres in 1 sample
McCuaig Lake = VERY CLEAR lake - 7.5 metres in 1 sample
The results for all years going back to 2010 are available on the following Government of Quebec website: http://www.environnement.gouv.qc.ca/eau/rsvl/relais/index.asp
We encourage you to check out this website.
Thank you to Stewart Wilson (Farm Lake), Nick Cushman (Hughes Lake) and Kim and Gord Robertson (McCuaig Lake and Little Hughes Lake) for devoting their time to taking the samples. We look forward to having a full set of results for all four lakes in 2019.
How we do Secchi Disk testing
A Secchi Disk is a black and white circular disk, 8" in diameter. The disc is mounted on a pole or line, and lowered slowly down in the water. The depth at which the disk is no longer visible is taken as a measure of the transparency of the water. GORA volunteers make periodic measurements and submit their readings to the Province.
While Secchi Disk readings do not provide an exact measure of transparency, they are an inexpensive and straightforward method of measuring water clarity. Secchi disk measurements are an integral component of the Province's lake water quality assessment programs.
