Native Colorado River cutthroat trout are not currently found in Little Muddy Creek, however there are good numbers of non-native brook trout. The stream may also contain a few mountain suckers as well as non-native creek chubs and speckled dace.

When dry, the roads to Little Muddy Creek are passable by most vehicles. However, when they're wet it's best to fish somewhere else for a day or so until they dry out. Of the several ways to reach Little Muddy Creek you can go south from Rawlins on the Deep Creek Road. In about 27 miles, turn right (southwest) on the McCarty Canyon Road. Follow this road for about 5 miles to its junction with the Miller Hill Road. Take this road northwest about 4 miles to where it forms a "Y" at the bottom of a steep hill. Take the right hand fork and go a little over 4 miles. Little Muddy will be on the right parallel to the road and about 1/2 mile away. You can take any of several two-track trails to the stream though you'll need a high clearance vehicle.
