Fish San Juan County's high lakes and side creeks, and know the upper Animas

San Juan County rewards anglers who know where to cast. Many tributaries and high lakes in the surrounding mountains fish well, so a trout day up here is very much on the table. The trick is matching the water to the spot.

The main-stem Animas in its highest reaches is the exception, and there is a clear reason worth knowing. For more than a century, mining left behind workings that drain metal-laden water into the high creeks. Studies by federal agencies have found that tributaries like Cement Creek and Mineral Creek add iron, aluminum, zinc, and copper to the Animas near town. In some reaches above and below Silverton, those metals have reduced or wiped out trout populations, with only limited fish surviving in places.

So the river runs right through Silverton, but the upper stretch is mining-shaped rather than a classic trout stream. Plan around it: aim your lines at the high lakes and side creeks, and you will find better water.

Wherever you go, treat regulations and any health advisories as the deciding word, not local lore. Rules and water conditions can change over time.

For current fishing rules by water and any fish consumption advisories, check Colorado Parks and Wildlife and the state health department before you fish the Animas.
