Mountain Laurel Trout Unlimited Hatch Chart
Hatches are not an exact science but we hope the below chart will assist you in your fishing.
Due to the fact that MLTU has mountain and valley streams, hatches may differ from a few days to weeks, from stream to stream. Don’t forget your terrestrial patterns for summer and Streamer patterns can be effective any time of the year.
