Dickson Lake?

Anyone pass through Dickson Lake last year? I went through in October 2106 and it was still pretty soupy, just wondering if it appears to be getting any better.

I don't think they released any information over the winter months. The last advisory from the park regarding Blue Green Algae was the presence of Algae in Opeongo and Lake of Two River. That is in addition to the problems in Dickson, Hardy Bay and Ryan.

It unfortunately appears to be getting worse, not better.

Re: Dickson Lake?

That's too bad, hopefully it will run its course at some point. I saw on the friends of Algonquin Park website that they took sediment samples in 2015 to determine if it was part of a natural cycle but I haven't seen any results posted. Dickson was one of my favorite lakes in the park and I'd like to spend some time there again, shame about Opeongo and others as well, lets hope it doesn't get too wide spread.

Re: Dickson Lake?

I am told that the various cyanobacteria species that caused the bloom conditions in many lakes affected in Ontario have been present in the lakes since the ice age, but for some reason their numbers have increased. One of the researchers working on Dickson Lake will be present at Meet The Researcher Day to explain her work and answer questions.

Re: Dickson Lake?

We paddled through Dickson lake from the 90m portage of Hardy's Bay/Lavieille to the 4895m to Round Island in mid August, stopping at a few campsites and taking in the lake in a meandering path to take in as much as we could of the lake while also trying to be as careful as we could.  We carried a 20 litre dry bag and our 4 litre filter bag full of water from 'northern' Lavieille juuussst in case we ended up wind bound, or something unexpected happened. 

I was expecting large 'blooms' of algae floating on the surface of the water like I've seen on Lake Erie in the past. We saw no visible sign, though I'm certain our visual inspection and sample size of one doesn't mean things have cleared up by any means.  The water 'appeared' to be very clear in every section we visited.  In any case, the campsites we stopped at certainly appear like they are enjoying the break!

Re: Dickson Lake?

So I was just looking for any updates on this and the official park website does't have any. No updates on here since fall 2018. Anyone care to post firsthand accounts from 2019 or links to official reports that I couldn't find.

I suspect this is basically the new normal for the area, but am hopeful as always.
