  • Ennis Lake is accessible year round.
  • The Lake is located 10 miles northeast of the town of Ennis.

  • On the Lake and in the area, you can enjoy fishing, water sports, and wildlife watching.


Known by longtime locals as Meadow Lake ( the Forest Service renamed it long ago), Ennis Lake was formed in 1905 when Montana Power built a dam on the Madison River at the head of the Bear Trap Canyon. The lake is shallow -- an average of 8 feet deep; 20 feet at the deepest -- which means the water is warm, just right for water sports particularly in the morning before the wind comes up, and windsurfing in the windy afternoon.


Ennis Lake is located northeast of the Town of Ennis.

From the town of Ennis, travel north along US highway 287, approximately 6.5 miles. At the McAllister Junction, turn right onto Ennis Lake Road and travel another three miles.
