Well I don't plan on moving the location of anything but there are certainly lakes around. Too bad every lake is a half hour drive at least and the Juniata is a 30 second walk.
The Juniata will most definitely not be fishable for the jam. It was starting to look good and I thought we were in for more dry weather but apparently I was wrong. Smaller warm water streams like the Aughwick and Tuscarora may be fishable, there is plenty of trout water around that may accommodate some anglers, and, as Frederick pointed out, lakes. The closest lake is Raystown but Colyer, Faylor, Walker, and Poe Paddy are all within a relatively short drive. This year sucks and we've been dealt a bad hand.
