Trout anglers divide aquatic systems into three types; still waters, tailwaters, and rivers. In the spring, fishing is most successful in still waters and tailwaters. This statement should not be seen as an insult to fishing small streams and rivers, like the Logan or Blacksmith Fork, at this time of year. The challenge with these unregulated systems during the spring is they are often frigid and their flows are unpredictable. Furthermore, the pristine settings of these smaller more remote streams and rivers are best enjoyed during the summer. There are several well-known to exceptional tailwater fisheries within a half days drive of Cache Valley. Stream reaches below dams on the Green, Snake, Provo, Weber, Beaverhead, Big Lost and Henrys Fork Rivers can all be great fisheries in the spring. Exactly when depends upon the timing and magnitude of the flow released from the dam and whether quickly melting snow is entering downstream tributaries and clouding the water.
