Underwater River Scenery Pictures, Page 4

Here's the underside of a "lunker structure", a manmade undercut bank where trout love to hang out. It's amazing how much I've seen the trout use these things. I've also noticed that the best trout populations I've seen are in streams where lunker structures have been installed.

Underwater moss and riffle bubbles.

Here's the stream bottom of a newly renovated artificial channel created by the Wisconsin DNR to restore the natural flow of a small stream that had previously been diverted through a series of shallow, water-warming old private hatchery ponds.

Light beams filter through a wavy surface.

Even in the winter there's some green weed growth at the bottom of a healthy trout stream.

I took this picture of the underside of a large slab of ice in a northern Wisconsin river in early February. I got cold.
