In which I field a bunch of excellent questions.
I have taken the liberty of transcribing this, below the fold.
Nearly an hour of long underwater camera shots, with the natural water sounds which folks find so soothing about this footage. Fish occasionally swim through. Also a couple mergansers towards the end. Put this on, go make some tea, and chill.
I got a distress call the other day. A citizen fan of my Lake Superior Aquaman page wrote me saying, “While swimming in the Lester River (at the spot where it’s like a little swimming hole, right before the first bridge that leads to the park) my husband dived off one of the rocks and lost his glasses. Another younger boy lost his goggles… what are the chances that they fell into the bottom of the hole made by the waterfall? We tried to go down but I couldn’t see or hold my breath that long lol.” So I offered to help, for am I not … Lake Superior Aquaman?
Not much happened for 45 minutes at 15+ feet deep, but I did get this. Going back today! This is the area shown in this video where there is a channel between two giant boulders. I wedged the camera-on-a-stick between some rocks and left it there. Lots of boat traffic not too far away and that is the noise you hear. Fish Cam pt. 1 here.
I saw a family of mergansers diving in shallow water (~18 inches deep) by these rocks where I’d seen little fish before. After the birds had gone, I set my camera down there for an hour and 40 minutes in three different locations. Here I have condensed all the fish that swam by = three minutes of footage. If you wonder what mergansers eat, this is like a drive-thru restaurant for them. I would appreciate any help with identifications, there are at least 4-5 species represented.
Responding to a comment about how some of the fish seem curious about the camera, part of the reason may be it is simply blocking their way. This area of interspersed boulders is a maze-like bunch of trails for them to zoom around in all day. To keep my camera from floating, I had to pile rocks on top of it, essentially blocking one of their thoroughfares. Several fish come up to it in transit and squeeze over top of it or around, others turn back and go the way they came, adjusting their regular routes.
Lastly I will add that several times, pairs of fish (I don’t know what kind they are) seem to be playing. I think these may be the same pairs each time they appear. I have named the most prominent ones Herbert and Gerbert.
