Big Horn River

A classic dry fly stream, flowing right through the town of Thermopolis. This stream has several long stretches of slow meandering water holding big fish that love to eat small dries, often rising in pods and are so prolific that a pod of fish in a deep run will actually be mistaken for a shallow riffle.

This river also has several beautiful nymph runs, and some very deep pools that hold some big fish.
