especially close to the northern dams and smallmouth bass are caught in slower stretches. From Berlin New Hampshire to the Maine border the river is a mix of riffles and dry fly glides. The many mountain streams in this stretch provide spawning habitat for a healthy population of wild rainbow trout. Stocked, wild, and holdover browns, brookies and LL salmon can also be found in this water. Dry flies, nymphs and streamers are all important tools to effectively fish the Andro.
