Red Lake Secchi Disk ?

[RLS]

Is there a secchi disk or clarity reading for Red Lake Ontario?

Here you go!

 

Kdx SD = 2.5 (Product of the vertical attenuation coefficient and the depth at which the Secchi disk disappears)

EZD : SD = 1.48 (Ratio between depth of 1% light and depth that the Secchi disk disappears)

Isu : I = 2.8 (Amount of incident PAR remaining at the Secchi Disk depth, %)

 

Cheers,

Tony

Thanks for the reply.

The above data is confusing to me. :-(

The disk readings I am used to are a measurement, usually in feet.

ahh memories of limnology 400...I feel like I'm 23 again.

 

I think you'd also need a date as the SD depth would be changing as the water gets warmer
