This large, remote reservoir can be difficult to get to, and high clearance helps. However, it is an excellent lake for ducks and other waterbirds, and since it is a fairly deep lake, it can be a good spot to look for loons and divers in migration. MacFarlane is also one of the few places in Colorado where American White Pelicans breed, and is an excellent spot for various raptors as well. The drive in passes through extensive sage flats, and there is a decent chance at stumbling upon a Greater Sage-Grouse. Elk abound in the area, and an occasional moose is sometimes seen. Note that access to this site can be very difficult in the early spring, when there is still snow on the ground, or after a heavy rain.
Directions: from Walden, travel south on SR-125 to CR 28 and take a right (west). Go about 2.3 miles to a two-track on the right. Follow this for approximately 4 miles, following signs for 'MacFarlane Reservoir Access' to the reservoir.
