Since options to dive in the Lake became a little restricted, the opportunity was taken today to go and revive acquaintance with Upper Brewer's Mills. As the accompanying video illustrates, conditions were less than ideal. For whatever reason (and it's hard to see where the flow is coming from) there was a healthy current flowing down the channel. This led to the adoption of the tried and tested 'spin cycle' dive experience. Entry was made in the usual place and an immediate descent to the bottom of the bowl allowed a few minutes to have a look around before allowing the current to take us, counter-clockwise, around the shallow margins and back to the entry point. Rinse and repeat three times for a total of just over 30 minutes in water at 34F (2C). The air temperature was -4C (24F) and only one, rather frozen-looking Perch was spotted throughout the dive. Novices are advised to avoid this dive site when a noticeable current is running. It is possible to be carried out of the circular current flow and swept downstream.
The lake levels in Rideau Canal are being dropped due to the high water levels currently.
