Flows on the Animas have come down from runoff highs and should stabilize soon enough. As such, water clarity has improved and will continue to do so, absent heavy rain which often leads to some discoloration. With lower flows and the summer heat comes dangerously warm water temps, however. So be sure to keep a thermometer with you or play it safe if the water feels too warm, particularly in the afternoon, and get off the river. Otherwise, you can check water temps on the DWR website for real time data. Nymphing with some combination of searchers/attractors and imitations will do most of the heavy lifting. Ensure plenty of weight and adjust depth until you hone it in. However, you can’t go wrong with dry flies, streamers or dry droppers. A big stimulator fly like a Chubby Chernobyl or Amy's Ant to one or more droppers should entice a few eager trout as well. Trout are stacking up along the banks and moving in and out of the outer seams to feed. Caddis, sallies, midge and baetis are all on the menu so come prepared to fish the kitchen sink.
The Animas is a freestone river that originates high in the San Juan mountains in southwestern Colorado and spans over 126 miles before reaching the San Juan River in the northern town of Aztec, New Mexico. From the confluence of the West and North fork, the river travels south through Eureka and Howardsville, Colorado, before turning southeast to Silverton. From Silverton, the Animas travels due south through the Animas Canyon along the Silverton Narrow Gauge Railroad to the town of Durango. The stretch through the town of Durango was recently recognized as a Gold Medal Water and is arguably the best place to fish. The Animas is a large river with some sections spanning 100 feet wide. It is home to a number of trout species, but is most known for its rainbow and brown trout. While the majority of the trout you catch will be in the 18 to 20 inch range, it is home to some of the state’s biggest browns.
With the exception of early spring run-off, the Animas can be fished year round as the river doesn't freeze over given comparatively mild winter weather. Float fishing, via raft or drift boat, is a great way to go, but you are limited to a short window (late spring to early summer) depending on flows and snowpack. Otherwise, wading is another highly effective method of fishing. Wading allows you to take your time fishing the nooks and crannies and really seek out those trophy trout. Sight fishing is a must in times of high water clarity as these trout can be fairly skittish and selective. While freestones are often forgiving, the Animas can be humbling even for the most experienced angler. As far as aquatic bug life goes, midges are present year round and will entice trout in both nymph and adult dun (dry fly) form. In the spring and fall you’ll find BWOs and damselflies among other cross seasonal hatches. In summer, caddis are abundant, but you’ll also find PMDs, golden stoneflies, yellow sallies, green drakes and various terrestrials in the water. During this time, the hopper dropper action is particularly effective, but you can’t go wrong with a nymph rig, similar to the rest of the year. In fall and spring, streamers are effective as trout are particularly territorial and aggressive given spawn activity.
There are a number of great walk-in access points, but the easiest and most popular stretch is in the town of Durango. There is a seven mile stretch that starts at the 32nd bridge and runs all the way down to the Rivera bridge where you’ll find easy parking and public walk-in access. Otherwise, wading access is tricky inAnimas Canyon and south of Durango.
The most popular stretch to float is through town as it is all public water, allowing you to anchor down and get out of the boat and fish. There are a number of put-ins and take outs between the 9th Street boat launch/takeout and the Animas River takeout south of town. Otherwise, you can access the water via the Trimble Boat launch and takeout, north of town, in Animas canyon. This section see’s less pressure as it is mostly private. With this in mind, you cannot anchor down in private water and if flows are too low to float through without portaging, you may get yourself in trouble with landowners or Johnny Law.
