Tennant Lake

Tennant Lake (Whatcom County) is a shallow, 80 acre peat bog in Tennant Lake Park, located about one mile southeast of Ferndale. There is an interpretive center and observation tower at the park's entrance, close to the Fragrance Garden that contains a living collection of dozens of herbs. Tennant Lake can be reached by walking along the boardwalk over the wetland that surrounds the lake. The water can become nearly covered in summer with yellow pond lilies. The lake is closed from Oct. 1 to Jan. 31 for the waterfowl hunting season.
