Most ice-eaters ("bubblers") direct water upwards, which has little effect on the bottom-dwellers known as
benthic macroinvertebrates. ("Benthic" meaning
bottom).
It's the "stirring" part that harms the lake's
benthic macroinvertebrates.
In the chart below (credit: "Bigpicturebiology), macroinvertebrates that convert organic waste are shown, with their importance to the lake pictured from top to bottom. (Caddis Fly, Damselfly and Mayfly are plentiful in Winter Harbor, so I guess we're doing well
there).
Much overlooked are those pictured as "Scud". They are a form of fresh water shrimp, and can be found feeding among the lake's organic debris. If disturbed, they will "swim" up-side down. (Normal for Scud—and
Krill).
Leave a coco-fiber doormat in the lake for a few days, and there will be hundreds dropping off when you go to retrieve it.
