Brown Trout
If you're chasing brown trout near Johnstown, Colorado, the nearby Big Thompson River offers some excellent opportunities. This river, known for its challenging flows and diverse structure, holds a healthy population of browns that can be quite receptive to various fly fishing techniques. The best time to target them is during the spring and fall when water temperatures are moderate, and the fish are actively feeding. Look for deeper pools and undercut banks where browns often lie in wait. Access can be tricky in some areas due to private land, but there are several public access points along Highway 34. One local tip: be prepared to nymph with small patterns as the browns in this area can be quite selective. Also, keep an eye on the river flows as they can fluctuate rapidly due to irrigation demands.
