While the Salmon River isn't a Lehigh Valley Trout Stream, I had to include it because its one of my favorite big fish streams. The Salmon River is located about 3 hours north of the Lehigh Valley and worth every minute spent getting there. If you yearn to catch big fish....don't miss a chance to go to the Salmon River! Chinook average 20-30 lbs., Coho 8-12 lbs., Steelhead average 8-10 lbs. and Browns can top the scale at 15 lbs. or more!
