Fern Ridge Lake lies behind Fern Ridge Dam, near Veneta, Oregon. It has a somewhat muddy bottom, so the color of the water. Along the eastern shore to the left side of the lake here, there is the Fern Ridge Wildlife Area, where I have spent many enjoyable hours. A variety of migratory birds stop here at various times. There is a birdwatching platform in the midst of the area.
