Have been there a few times. The state park has campgrounds above and below the dam. The San Juan River below the dam has 3.5 miles of
Special Trout Waters that are fly fishing only/catch and release. The area adjacent to the Cottonwood Campground is not in the Special Trout Waters and is heavily stocked. You can see the
stocking reports on line. It is a pretty good size river and not all that easy to fish from the bank. There are a number of guides that offer float services. Being a tailwater fishery it is more subject to the release schedule of the dam than season or weather.
