Little Juniata River
At Tyrone, the river receives the southern Bald Eagle Creek, then turns abruptly southeast, passing through a water gap between the Brush and Bald Eagle Mountain ridges and enters Sinking Valley where it receives Sinking Run. Approximately 6 miles (10 km) northwest of Huntingdon, near Petersburg, it joins the Frankstown Branch Juniata River, forming the Juniata River.
In colonial America, the river was used to float freight downriver on boats called "arcs". Shipments were placed on board in Birmingham, just east of Tyrone, to await water high enough to clear the rocky stream bed. Thus the Little Juniata was (and still is) listed as a commercially "navigable" river.
The Little Juniata River is a good spot for fly fishing; it holds a Class A population of wild brown trout and requires no stocking.
