the little lehigh is in the lehigh valley and is 1 spring creek of several in the area that will be fishable throughout the summer. Fishing is best in the Am for tricos/late evening for sulphers and whatever else is hanging around into the summer months. With flows being so so this spring, I'd intend on heading to the lehigh valley, its less than a 2hr drive, will have solid surface activity, and you won't be risking the health of the fish barring an extremely hot June. It won't be easy, but its fun fishing that time of year because you can see a ton of fish in the streams, they just don't get fooled very easily
