Brown Trout
While Longmont isn't exactly known as a brown trout mecca, some surprisingly good fishing can be found within a short drive. The St. Vrain River, particularly the sections upstream towards Lyons and Estes Park, holds a decent population of browns. While these aren't trophy-sized fish on average, the opportunity for a productive day of fly fishing is definitely there. Spring and fall are generally the best times to target them, as water temperatures are more favorable. A local tip is to focus on the deeper pools and runs, especially those with good cover like overhanging vegetation or submerged logs. Also, be aware that the St. Vrain can experience periods of high water and turbidity, especially during spring runoff or after heavy rain. Check river conditions before heading out. The browns here can be picky, so carry a variety of flies and be prepared to experiment.
