The north side consists mainly of douglas fir and ponderosa pine mixed with lesser amounts of poplar, alder and common and mountain juniper. The south side of Loon lake is composed mainly of englemann spruce and douglas fir. The entire length of the west shore has many resorts and summer residences. There are some cabins on the east shore, a ranch on the north east end and an indian reserve to the southwest.
