Ellis lake is a beautiful man-made lake located smack dab in the middle of Marysville city. The lake is surrounded by Ellis Lake Park and a paved walkway dotted with old fashioned lighting. Pedal boats and Kayaks meander the lake, people fish, and there are tunnels for crossing under the roads. There are a few islands in the center of the lake, one called Gazebo Island and another North Ellis Lake Island. Geese, ducks, blackbirds, and various other birds can frequently be seen around the lake.
