The Trent Aquatic Research Program 2020 report on Chandos Lake is out, and with permission from Dr Paul Frost, can be found under the Chandossier.com “Chandos Water Quality” menu tab. Or, via this direct link.

Katrina Moser, the scientist from Western whose lab has been carrying out research on our lake, has forwarded the following clip relating to the decline in lake oxygen levels and its effect on fish.

The KLSA has just released their 72 page 2020 report. It seems beyond excellent, and there seems much here to inform our own stewardship efforts at Chandos. Once I’ve had a better look, I shall try and highlight material that may be useful to us.

The recent interest in the radon health concern has resulted in some questions about radon’s origins. As we know, there is a concern about radioactive radon gas in dwellings, especially those in the Canadian Shield, such as those at Chandos.  Where does this radon come from?  This note attempts to be a bit of a primer on the subject.

The decay of uranium-238 into the radioactive gas radon-222.

The Kawartha Lakes Stewards Association’s 2021 spring meeting is available for viewing on Youtube, It is about 1 hour long.

The KLSA represents many lakes on the Trent Severn Waterway. They are very active, and their work is always of high quality. More on the KLSA can be found here.

Radon is the second leading cause of lung cancer, after smoking, but is first amongst non-smokers. Radon is a byproduct of the natural decay of uranium, which is a common element in the Canadian Shield. It is a radioactive gas that seeps up from the ground and enters the dwelling though cracks in concrete, open crawl spaces, and even through the water supply from a well. A well-ventilated dwelling may dilute the radon to a safe level, but a “tight” dwelling will allow it to accumulate and build up to hazardous levels.

Here is an interesting flowchart showing how all the TSW lakes are connected.

Note that area lakes Jack, Anstruther, and Eels are all TSW reservoir lakes.

It is true that Chandos Lake flows into the Crowe River, and that the Crowe River eventually enters the Trent River near Campbellford. There is a dam on the Crowe River at Marmora, that primarily controls the level of Crowe Lake. The operation of this dam has negligible effect on Chandos because the difference in elevations is about 130 metres, and between Chandos Lake and Crowe Lake there are many natural areas (wetlands, etc), to store water.

Iain Gorman forwarded me some correspondence he received regarding low lake levels in the region.

It is duplicated below, in Italics,

First though, an explainer….

Cathy Burgess reports that the official date for Ice out in 2021 is April 9.

The winner of her contest is Brian McKinlay. I understand his prize is some very old ice cubes from the last ice of 2006, which pair very nicely with 15 year old Single Malt Scotch.

A new graph has been posted as per below. It can be seen at chandossier.com along with a bit of commentary.

The following is a post to the CLPOA facebook page….

Following up on Iain’s post of April 2, 2021 where he reports that the flow along Flat Creek is into the lake: –It seems as of April 3, the reverse flow has “reversed” and is back to a normal outflow from the lake. On March 25, the lake level was 1026′ 3″. The first log was pulled out of the Paudash dam on that day, with a log being pulled on March 26 and March 28. The Chandos lake level peaked around April 1 just over 1027′, and as of 3 April it is about 1027′ 0″. In 2020 the peak of 1027′ 6″ occurred about April 6. Unless there are some really crazy rains in the next week or so, we have likely passed our peak water for 2021.
