Ennis Lake is a man made impoundment of the Madison River in southwestern Montana. A shallow lake, much of the water is less than 8 feet deep. Ennis Lake is well known for its "gulper" hatch of callibaetis and trico mayflies during the summer. Large Browns and Rainbows of over 20" can be taken on the surface during this time. The lake has many weed beds, and the trout will cruise around the edges and lanes between these weeds hunting for food. Much of the fishing on the lake is sight fishing, especially when the wind is cooperating. Shore fishing is limited here, so a boat is nice.
